What are Proximity Groups
Xton Access Manager (XTAM) can be configured with multiple session manager modules and proximity groups are used to determine which Session Manager is used to serve each remote endpoint(s). Proximity groups can use an IP range (i.e. 10.1.1.x/24) or Host Mask (in RegEx form i.e. (.*)\.contoso\.com) or Vault Name in order to determine where the session communication is sent.
For additional information about why you may consider deploying multiple session managers, please read our blog post on this topic here: Deployment Architecture to Scale Session Manager
Once you have two or more Session Manager modules deployed, you will then need to create your proximity groups. For example, computers from the network 10.0.0.x/24 will be served by Proximity Group A while computers from the network 10.1.1.x/24 will be served by Proximity Group B.
Login to XTAM as a System Administrator
Navigate to Administration > Settings > Proximity Groups
Click the Add Group button
Enter a Group Name to easily identify this Proximity Group
Choose the Selector, either IP Range, Host Mask, Vault Based, Folder Based or Composite.
Click the Add Server button
Enter the Host Name where this remote Session Manager module resides
Enter the Port value of 4822 (default) or the value that was configured.
Note that you can add multiple session manager servers to a Proximity Group in order to enable XTAM load balancing.
Click the Create button to save this group
Once saved, the Proximity Group will be created and XTAM will automatically check its connectivity. If the communication channel is successfully established, the Servers value will be displayed in blue, if it is successful and secured it will be displayed in green and if it failed to connect it will be crossed-out. Your Proximity Group is working when either blue or green, crossed-out will need to be resolved.
Ensure that port 4822 is open between XTAM and your remote session manager server.
You can repeat this process as many times as needed to configure additional Proximity Groups.
