The procedures below provide an example of setting a new Firewall rule in a GPO and applying it to a Linux Agent. For this example we already have a custom OU that contains our Linux Agent.
For information about opening the GPEdit Extension snap-in on a GPO, see Accessing or Creating Group Policy Objects.
To create a Linux Agent Firewall GPO in the AD Bridge GPMC snap-in:
Right-click Group Policy Objects in the domain tree, and select New to create a new GPO.
Right-click the new GPO and select Edit to open the GPO editor.
Expand Linux Settings in the GPO editor, and click the Firewall node.
Click + to open the Rule drop-down menu in the AD Bridge snap-in, select Allow HTTP from the Rule list, and click Save to enable the new rule.
You can also create custom Firewall rules to block or allow Inbound or Outbound traffic based on port, protocol, or IP address.
To add a custom Linux Agent Firewall rule in GPMC:
Expand Linux Settings in the GPO editor, and click the Firewall node.
Click + to open the Rule drop-down menu in the AD Bridge snap-in, and select Custom Rule from the Rule list.
Use the Firewall Rule dialog box to name and configure the Action, Direction, Port, Protocol, and IP Address for the custom rule.
Add and save your changes.
To apply a new or modified GPO to one or more Linux agents:
Select the GPO with the new or modified Linux setting and drag it onto the OU that contains the Linux Agent(s).
Click OK to link the GPO to the OU and apply the policy to any applicable Linux Agent computers.
NOTE:In order for the policy to be applied to Linux Agent computers, the Linux Agent Service must be running on those devices. If the service is not running, use one of the commands below, applicable to the platform, to start the service:
systemctl start adb-agent.service
service adb-agent start
