3.0 Ziti services

3.1 Introduction

In this guide, we will demonstrate ziti services with three examples:

• connection between two identities running ziti-edge-tunnel (Network Diagram 1)
• connection between ziti-edge-tunnel and a ziti-router (with tunnel enabled)(Network Diagram 2)
• connection from a non-OpenZiti endpoint using router as GW(Network Diagram 2)

3.1.1 Network Diagram 1

3.1.2 Network Diagram 2

This guide provides both CLI and GUI (ZAC) instructions. To use ZAC, make sure ZAC is installed. If you have not installed ZAC, and would like to use it in this section, please follow the ZAC Setup Guide before continue.

3.2 Setup VMs for ziti network

3.2.1 Controller

3.2.1.1 ZAC

Please make sure you can login to your network and see the welcome screen before continue.

3.2.1.2 CLI

You will need to login to controller to provision identities and service. Please make sure you are performing the action on the right node.

On the controller, before performing the CLI command, you will need to login first:

zitiLogin

The login token expires after some period of time. If the token expired, you will need to login again via the same command. You will see error message like this when the token expired:

error: error listing https://161.35.108.218:8441/edge/management/v1/config-types?filter=id%3D%22host.v1%22 in Ziti Edge Controller. Status code: 401 Unauthorized, Server returned: {
    "error": {
        "code": "UNAUTHORIZED",
        "message": "The request could not be completed. The session is not authorized or the credentials are invalid",
        "requestId": "7zxWCy7Vx"
    },
    "meta": {
        "apiEnrollmentVersion": "0.0.1",
        "apiVersion": "0.0.1"
    }
}

3.2.2 Router

We need two routers to complete our example in this guide.

• Public Edge Router (pub-er) was setup in the Router setup section, this router provides fabric and edge connection. It does not have tunneler functionality. Make sure you also modify the Firewall for this router.
• Local Edge Router (local-er). Please follow the Router guide to setup a Router with edge listener and tunneler. For this router, you will need to setup Resolver, Route Table, Source and Destination Check and Firewall.

3.2.2.1 ZAC

On the ZAC ROUTERS screen, you can check your router and make sure it is created correctly. You can also check the identity associated with the router by clicked on IDENTITIES

On the ROUTERS screen, you will see two routers we created.

On the IDENTITIES screen, you will see an identity match "local-er" router name. If you perform the provisioning correctly, you should not see an identity name "pub-er".

3.2.2.2 CLI

You can also check the provisioning on the controller.

You should see two routers named pub-er and local-er

# ziti edge list edge-routers
╭────────────┬─────────────────────────────┬────────┬───────────────┬──────┬────────────╮

You should also see an identity named local-er

# ziti edge list identities

╰────────────┴─────────────────────────────┴────────┴────────────┴─────────────╯
results: 1-3 of 3

Since the pub-er is also a link listener, you should also check the link listener function is correctly setup. Check the router on fabric to make sure it has LISTENERS (tls:****) displayed for the pub-er.

3.2.3 Tunnelers/Identities

We need two tunnelers for our testing. Please follow Create a VM section of the Controller Guide to create two VMs running Ubuntu 22.04.

3.2.3.1 Create Identity with ZAC

To create Identities on ZAC, go to the Identities screen, and press + icon. On the CREATE IDENTITY widget, enter the NAME of the identity (Required and has to be unique). Leave the IDENTITY TYPE as "Device". Leave the ENROLLMENT TYPE as "One Time Token". Fill in other optional fields and press SAVE.

Create two identities:

• ingress-tunnel
• egress-tunnel

Once the identities are created, you can check the identities and download the JWT from the MANAGE IDENTITIES screen

3.2.3.2 Create Identity with CLI

Create two identities (ingress-tunnel, egress-tunnel) on the controller:

ziti edge create identity device ingress-tunnel -o ingress-tunnel.jwt
ziti edge create identity device egress-tunnel -o egress-tunnel.jwt

3.2.3.3 Register Identities

Login to your VMs created earlier, follow Install Linux Package Ubuntu Jammy 22.04 section to install and register your ziti-edge-tunnel.

After the tunnel is registered, check the status and make sure it is running

# systemctl status ziti-edge-tunnel
● ziti-edge-tunnel.service - Ziti Edge Tunnel
     Loaded: loaded (/etc/systemd/system/ziti-edge-tunnel.service; enabled; vendor preset: enabled)

3.3 Create Edge Router Policy

By default, the system created an edge router policy to bind all identities to any routers tag with #public attribute. So, we need to add #public to our router (pub-er).

3.3.1 ZAC

From the ROUTERS screen, you can choose Router Policies to display the edge router policies. As you can see, the default policy is already in place.

To add attribute "public" to the router, choose your router from the ROUTERS screen, click on ... and choose Edit

On the EDIT EDGE ROUTER screen, you can add public attribute and then press SAVE

3.3.2 CLI

On the controller:

Check the edge router policy. Make sure "allEdgeRouters" policy is present.

# ziti edge list edge-router-policies

3.4 Setup Tunnel to Tunnel ssh connection

In this section, we will be showing how to configure ziti to establish ssh service via our network. We will be using a pseudo dns name (t2tssh.ziti) to establish this connection. The intercept side (ingress) will be ingress-tunnel, the server side (egress) will be egress-tunnel.

For CLI procedures, all commands are done on the controller

3.4.1 Create a host.v1 config

This config is used instruct the server-side tunneler how to offload the traffic from the overlay, back to the underlay. We are dropping the traffic off our loopback interface, so we use the address "127.0.0.1“

3.4.1.1 ZAC

Create the configuration from MANAGE CONFIGURATIONS screen.

3.4.1.2 CLI

ziti edge create config t2thostconf host.v1 '{"protocol":"tcp", "address":"127.0.0.1", "port":22}'

3.4.2 Create an intercept.v1 config

This config is used to instruct the intercept-side tunneler how to correctly intercept the targeted traffic and put it onto the overlay. We are setting up intercept on dns name "t2tssh.ziti"

3.4.2.1 ZAC

Check the provisioned configs on the configuration screen:

3.4.2.2 CLI

ziti edge create config t2tintconf intercept.v1 '{"protocols": ["tcp"], "addresses": ["t2tssh.ziti"], "portRanges": [{"low": 22, "high": 22}]}'

If the command finished successfully, you will see two configs:

# ziti edge list configs
╭────────────────────────┬─────────────┬──────────────╮
│ ID                     │ NAME        │ CONFIG TYPE  │
├────────────────────────┼─────────────┼──────────────┤

│ gIeZ1KgilGXzkY4RxDF2f  │ t2thostconf │ host.v1      │
╰────────────────────────┴─────────────┴──────────────╯
results: 1-2 of 2

3.4.3 Create Service

Now we need to put these two configs into a service. We going to name the service "t2tssh":

3.4.3.1 ZAC

Create service from Services menu from MANAGE EDGE SERVICES screen.

3.4.3.2 CLI

ziti edge create service t2tssh -c t2tintconf,t2thostconf

Check Service

# ziti edge list services
╭───────────────────────┬────────┬────────────┬─────────────────────┬────────────╮
│ ID                    │ NAME   │ ENCRYPTION │ TERMINATOR STRATEGY │ ATTRIBUTES │
│                       │        │  REQUIRED  │                     │            │
├───────────────────────┼────────┼────────────┼─────────────────────┼────────────┤
│ CZJi5tDxTk8C8XymCbu7f │ t2tssh │ true       │ smartrouting        │            │
╰───────────────────────┴────────┴────────────┴─────────────────────┴────────────╯
results: 1-1 of 1

Please note, the Encryption = true and smartrouting are default setting.

3.4.4 Create Bind Service policy

Now we need to specify which tunneler (in our case, egress-tunnel)is going to host the service by setting up a bind service policy

3.4.4.1 ZAC

Create a service policy from MANAGE SERVICE POLICIES screen:

3.4.4.2 CLI

ziti edge create service-policy t2tssh.bind Bind --service-roles '@t2tssh' --identity-roles "@egress-tunnel"

3.4.5 Create Dial Service policy

Now we need to specify the intercept side tunneler (ingress-tunnel) for the service by setting up a dial service policy

3.4.5.1 ZAC

We should have two service policies created. The services name should match on two policies. One policy is Bind and the other ons is Dial. They should be set to different identities.

3.4.5.2 CLI

ziti edge create service-policy t2tssh.dial Dial --service-roles '@t2tssh' --identity-roles "@ingress-tunnel"

Make sure both policies are setup correctly：

# ziti edge list service-policies
╭────────────────────────┬─────────────┬──────────┬───────────────┬─────────────────┬─────────────────────╮
│ ID                     │ NAME        │ SEMANTIC │ SERVICE ROLES │ IDENTITY ROLES  │ POSTURE CHECK ROLES │
├────────────────────────┼─────────────┼──────────┼───────────────┼─────────────────┼─────────────────────┤
│ 3wATDMvDv1LBRlNrYgsrjf │ t2tssh.bind │ AllOf    │ @t2tssh       │ @egress-tunnel  │                     │
│ VKIyQz9ZWf0euSDRikNh0  │ t2tssh.dial │ AllOf    │ @t2tssh       │ @ingress-tunnel │                     │
╰────────────────────────┴─────────────┴──────────┴───────────────┴─────────────────┴─────────────────────╯
results: 1-2 of 2

You should also make sure the policy advisor display correctly:

# ziti edge policy-advisor services |grep t2tssh
OKAY : egress-tunnel (2) -> t2tssh (2) Common Routers: (2/2) Dial: N Bind: Y
OKAY : ingress-tunnel (2) -> t2tssh (2) Common Routers: (2/2) Dial: Y Bind: N

Make sure there is a "Dial" line and a "Bind" line. They are both "OKAY" and has at least 1 Common Routers.

3.4.6 Verify the connection

Login to the intercept side tunneler (ingress-tunnel) node, you should be able to ssh to the server (egress-tunnel) by using dns name "t2tssh.ziti"

root@ingress-tunnel:~# ssh t2tssh.ziti

3.5 Setup Tunnel to ERT http connection

Edge Router Tunnel (ERT) has combine router and tunneler function. In this section, we will demonstrate a connection between a Ziti-Edge-Tunnel (egress-tunnel) to a ERT (local-er)

The procedure is similar to tunnel to tunnel service, so please refer to that section for detail explanation of each step.

Please refer to Network Diagram 2 for our test setup.

3.5.1 Create a host.v1 config

3.5.1.1 ZAC

3.5.1.2 CLI

ziti edge create config t2ehostconf host.v1 '{"protocol":"tcp", "address":"127.0.0.1", "port":8080}'

3.5.2 Create an intercept.v1 config

Use ip (10.124.0.2) as intercept address

3.5.2.1 ZAC

And you should have two configs:

3.5.2.2 CLI

ziti edge create config t2eintconf intercept.v1 '{"protocols": ["tcp"], "addresses": ["10.124.0.2"], "portRanges": [{"low": 80, "high": 80}]}'

# ziti edge list configs |grep t2e
│ IlgnlM2srnU7s8C3hiLJA  │ t2eintconf  │ intercept.v1 │
│ uJUtyXI5XH1wSsSCiCARp  │ t2ehostconf │ host.v1      │

3.5.3 Create Service

Now we need to put these two configs into a service. We going to name the service "t2ehttp":

3.5.3.1 ZAC

3.5.3.2 CLI

ziti edge create service t2ehttp -c t2eintconf,t2ehostconf

Check Service

# ziti edge list services |grep t2e
│ 5FI8Aw0IQ7xaUMgH2rKvps │ t2ehttp │ true       │ smartrouting        │            │

3.5.4 Create Bind Service policy

3.5.4.1 ZAC

3.5.4.2 CLI

ziti edge create service-policy t2ehttp.bind Bind --service-roles '@t2ehttp' --identity-roles "@local-er"

3.5.5 Create Dial Service policy

Now we need to specify the intercept side tunneler (egress-tunnel) for the service by setting up a dial service policy

3.5.5.1 ZAC

Check two service polices:

3.5.5.2 CLI

ziti edge create service-policy t2ehttp.dial Dial --service-roles '@t2ehttp' --identity-roles "@egress-tunnel"

Make sure both policies are setup correctly：

# ziti edge list service-policies |grep t2e
│ 4XpyRyE6vKo2Rd2gb2x6il │ t2ehttp.dial │ AllOf    │ @t2ehttp      │ @egress-tunnel  │                     │
│ 6bGra4CxFtpe0GmTeACLy  │ t2ehttp.bind │ AllOf    │ @t2ehttp      │ @local-er       │                     │

You should also make sure the policy advisor display correctly:

# ziti edge policy-advisor services |grep t2ehttp
OKAY : egress-tunnel (2) -> t2ehttp (3) Common Routers: (2/2) Dial: Y Bind: N
OKAY : local-er (3) -> t2ehttp (3) Common Routers: (3/3) Dial: N Bind: Y

Make sure there is a "Dial" line and a "Bind" line. They are both "OKAY" and has at least 1 Common Routers.

3.5.6 Verify the connection

Login to the router (local-er), setup a file to send via http.

root@local-er:~# cat >hello.txt
                    ___ ___                  .___
                   /   |   \  ______  _  ____| _/__.__.

                         \/                   \/\/

This is hello from local-er.
root@local-er:~# python3 -m http.server 8080
Serving HTTP on 0.0.0.0 port 8080 (http://0.0.0.0:8080/) ...

Login to the intercept side tunneler (egress-tunnel) node.

root@egress-tunnel:~# curl http://10.124.0.2/hello.txt
                    ___ ___                  .___
                   /   |   \  ______  _  ____| _/__.__.

                         \/                   \/\/

This is hello from local-er.
root@egress-tunnel:~#

3.5.7 Conclusion

In this section, we demonstrated intercepting http (port 80) request to an IP address and forward the request to a remote http server listening to port 8080 via ziti network.

3.6 Setup Connection from a non-OpenZiti client

3.6.1 Introduction

In this section, we will demonstrate how to setup non-OpenZiti client to use the ziti service. Please refer to Network Diagram 2 for our test setup.

You need to create a VM (Non-OpenZiti-Client) in the same data center as "local-er" for this test.

The following conditions need to be met in order for this connection to work correctly:

• The non-OpenZiti client has to be in the same data center as the edge router.
• The edge router is created with tunneler enabled.

We are also need to do the following to successfully demonstrate the connection:

• Create host and intercept config
• Create service
• Create dial and bind policy
• Setup route on the non-OpenZiti client

We will create an intercept at 11.11.11.11:80 and e2thttp.ziti, and drop off at loopback address (127.0.0.1) of egress-tunnel port (80).

3.6.2 Create a host.v1 config

Used address 127.0.0.1 as host side destination, and port 80 as destination port.

3.6.2.1 ZAC

3.6.2.2 CLI

ziti edge create config e2thostconf host.v1 '{"protocol":"tcp", "address":"127.0.0.1", "port":80}'

3.6.3 Create an intercept.v1 config

Use a pseudo ip (11.11.11.11) and DNS name (e2thttp.ziti) as intercept address

3.6.3.1 ZAC

And you should have two configs:

3.6.3.2 CLI

ziti edge create config e2tintconf intercept.v1 '{"protocols": ["tcp"], "addresses": ["11.11.11.11","e2thttp.ziti"], "portRanges": [{"low": 80, "high": 80}]}'

# ziti edge list configs |grep e2t
│ 1ANNy88ovJL6vAW6AwNbiM │ e2thostconf │ host.v1      │
│ 5kXnoEoMrfReOou8lty9zj │ e2tintconf  │ intercept.v1 │

3.6.4 Create Service

Now we need to put these two configs into a service. We going to name the service "t2ehttp":

3.6.4.1 ZAC

3.6.4.2 CLI

ziti edge create service e2thttp -c e2thostconf,e2tintconf

Check Service

# ziti edge list services  |grep e2t
│ 2uphDaBfIo7ubj6GhV8r93 │ e2thttp │ true       │ smartrouting        │            │

3.6.5 Create Bind Service policy

3.6.5.1 ZAC

3.6.5.2 CLI

ziti edge create service-policy e2thttp.bind Bind --service-roles '@e2thttp' --identity-roles "@egress-tunnel"

3.6.6 Create Dial Service policy

Now we need to specify the intercept side tunneler (local-er) for the service by setting up a dial service policy

3.6.6.1 ZAC

Check two service polices:

3.6.6.2 CLI

ziti edge create service-policy e2thttp.dial Dial --service-roles '@e2thttp' --identity-roles "@local-er"

Make sure both policies are setup correctly：

# ziti edge list service-policies |grep e2t
│ 305novDIduhXPEmA8gawpM │ e2thttp.dial │ AllOf    │ @e2thttp      │ @local-er       │                     │
│ 5zfoMaXKNDe3uIih8YHEWa │ e2thttp.bind │ AllOf    │ @e2thttp      │ @egress-tunnel  │                     │

You should also make sure the policy advisor display correctly:

# ziti edge policy-advisor services |grep e2thttp
OKAY : egress-tunnel (2) -> e2thttp (3) Common Routers: (2/2) Dial: N Bind: Y
OKAY : local-er (3) -> e2thttp (3) Common Routers: (3/3) Dial: Y Bind: N

Make sure there is a "Dial" line and a "Bind" line. They are both "OKAY" and has at least 1 Common Routers.

3.6.7 Verify the connection

3.6.7.1 Setup Server Side

Login to the Client (egress-tunnel), setup a file to send via http.

root@egress-tunnel:~# cat >hello.txt
              _   _      _ _
             | | | | ___| | | ___
  _____ _____| |_| |/ _ \ | |/ _ \ _____ _____
 |_____|_____|  _  |  __/ | | (_) |_____|_____|
             |_| |_|\___|_|_|\___/


You have reached the "egress-tunnel".
<CTRL-D>
root@egress-tunnel:~# sudo python3 -m http.server 80
Serving HTTP on 0.0.0.0 port 80 (http://0.0.0.0:80/) ...

Login to the non-OpenZiti client machine (Non-OpenZiti-Client).

3.6.7.2 Test IP intercept

root@Non-OpenZiti-Client:~# curl http://11.11.11.11/hello.txt
              _   _      _ _
             | | | | ___| | | ___
  _____ _____| |_| |/ _ \ | |/ _ \ _____ _____
 |_____|_____|  _  |  __/ | | (_) |_____|_____|
             |_| |_|\___|_|_|\___/


You have reached the "egress-tunnel".
Bye.

3.6.7.3 Modify the resolver

The Non-OpenZiti-Client's resolver has to point to the local-er. So it can resolve the DNS name from local-er.

Azure

• Modify /etc/systemd/resolved.conf.
• Put local IP of the "local-er" into the file.
• For example:

DNS=10.5.0.4  #local private IP of the ER

NOTE, the IP address should match your Next hop in the route table

Restart the systemd-resolved service

sudo systemctl restart systemd-resolved.service

AWS

• Modify /etc/systemd/resolved.conf.
• Put local IP of the "local-er" into the file.
• For example:

DNS=10.5.0.4  #local private IP of the ER

NOTE, the IP address should match your Next hop in the route table

Restart the systemd-resolved service

sudo systemctl restart systemd-resolved.service

Google Cloud

• Modify /etc/systemd/resolved.conf.
• Put local IP of the "local-er" into the file.
• For example:

DNS=10.138.0.2  #local private IP of the local ER

NOTE, the IP address should match your Next hop in the route table

Restart the systemd-resolved service

sudo systemctl restart systemd-resolved.service

3.6.7.4 Test DNS intercept
