Manually configure the NAS IP address that the RADIUS client will pass
to the server when requesting authentication. Normally this is automatically
determined by gathering the IP address of the system on which Guacamole
is running; however, there are certain scenarios (as in running in a
Docker container) where specifying this manually may be useful.
