If needed, you can have multiple tunneled platform connections through the Supervisor station. Traffic on each connection consumes some amount of resources, but typically capacity exists.

Remember that tunneled platform connections are dependent on the running Supervisor station. Avoid any Supervisor station restarts (or stops) during critical tunneled platform operations, otherwise problems are likely to result.

Although not necessarily recommended, currently there is nothing preventing a “loop back” platform connection to the Supervisor platform itself, using only the HTTP port as configured in its WebService. In this case the “Host” and “Tunnel to” fields would both have the same IP address.

This is a “workaround” solution if a firewall connection blocks all ports (for example, 3011) except for that one HTTP port.
