Any way to forward port A to port B, all on the same server, without an external firewall/router ?

Unless its running as a router (ICS) then no. Normally, you can change port number via the application. So lets say youre running a website, but you want it on port 8080 instead of 80. You configure IIS or Apache or whatever, not the OS.

Okay.  
Will experiment with ICS.  
If fail, will change port on app.  
If fail, will install a Linux host next to system and forward using that.

Maybe a Windows port of netcat would work?

Don’t you mean RRAS rather than ICS?

Ah. Netcat. That looks like the ticket.
