¶ What is Windows Subsystem for Linux (WSL)
Windows Subsystem for Linux (WSL) is a feature of Windows that allows you to run a Linux environment on your Windows machine, without the need for a separate virtual machine
¶ Install WSL on a Windows Machine
WSL can be installed from the command line. Open a PowerShell prompt as an Administrator (we recommend using Windows Terminal) and run:
wsl --install
This command will enable the features necessary to run WSL and also install the default Ubuntu distribution of Linux available in the Microsoft Store. It is recommended to reboot your machine after this initial installation to complete the setup. You can also install WSL from the Microsoft Store.
Once Ubuntu is installed, you should see it as an installed program and launch (see screenshot below).
¶ Create a Cyber Gateway
To create a Single-Interface Cyber Gateway (CGW-SIF), follow the steps below.
- Navigate to the MSP admin console -> Client Workspace
- Click on Sites in the left menu bar → Add Gateway
- Make sure Single-Interface is selected
- Enter a Name for the cyber gateway, admin email to receive notifications or alerts
- Select User Groups if already created or skip if no there is no additional requirement, admin can add/delete user group association later also.
- Select HA yes, in case high availability is required
- Click Save
¶ Deploy the Cyber Gateway
- Copy the install command for the cyber gateway you just created as shown in the screenshot below
- Paste the install command in the machine's SSH console/terminal
- Press Enter
The CyberGateway deployment will start. At this time, you can leave the deployment running unattended. You will receive an email on the admin email that you specified earlier when the deployment is complete. You can also check the status of the cyber gateway in the Exium admin console. When cyber gateway is deployed successfully and connected, you will see a Green Connected Status as in the screenshot below.
Post successful deployment, subnet of the CyberGateway machine's interface will be added as a Trustpath automatically. It will be associated to “workspace” group category, i.e. all the users in workspace will be able to access the resources on that private subnet. You can edit group association any time as per requirement. You may create new user groups and associate them with the trust path.
Once the CyberGateway is deployed successfully and connected, you can start testing the Zero Trust Secure Private Access policies.
Additional trust paths can be added manually. In case additional trust paths have different next hops, then those can also be configured from admin console. In case additional trust path subnets are already accessible via Cybergateway's default gateway then next hop configuration is not required.
You can follow below steps to add additional trust path subnets with or without their next hop.
- Click on Zero-Trust Paths
- Select CyberGateway from drop down list
- Click on Add Trust Path
- Provide Network Destination or private subnet to allow access for remote users
- Provide Next HOP Gateway IP, if it is different from default gateway of CyberGateway machine
Make sure next hop gateway IP is accessible from CyberGateway machine, else route configuration will fail
- Select Allowed User Groups or leave workspace group associated in case whole organization is allowed to access that subnet
- Save the configuration [CGW will pull configuration, and routes will be added after few mins.]
- Additional trust path configuration can be modified later as per requirement or when the next hop changes
Do not add next hop configuration in the default trust path which is created automatically by CyberGateway post deployment.
¶ Uninstall CyberGateway
Uninstall can be done from admin console or using CGW CLI commands
¶ From Admin console
- Navigate to the MSP admin console -> Client Workspace
- Click on Sites → Cyber Gateways in the left menu bar
- Select the CyberGateway you want to uninstall and click on the icon show in screenshot
- It will take around 5 ~10 mins complete uninstallation
¶ On CyberGateway terminal using command line
To uninstall CyberGateway from CyberGateway system directly
- type “sudo -s” to switch to root in the WSL/ Ubuntu console
- Run following command on terminal to uninstall
cgw uninstall
