Hi Toby.
Complicated question, and a complicated answer !
If you’re just using a firewall, but the two networks are on the same subnet, or the two networks are routable without NAT / PAT, then this should be possible.
What typically can’t currently be done is:
Private Network (Surface) | Public Internet | Private Network (Rack)
but
Private Network (Surface) | Private Network (Rack)
Should be OK providing the firewall between the two networks isn’t also translating IP addresses / port numbers from the public side into a private address range. Many ADSL Modems / Routers incoperate this functionality.
Port in use for the port forward should be:
TCP Port 51321
UDP Port 51320 through UDP Port 51324 inclusive.
We are looking to improve the current restrictions for internet connectivity for 1.50.
Hope this helps.
