Actually - now I understand this bit of port forwarding, it raises another question in my mind.

If I have 2 units in my network using port 12078, I can address them with, say, 192.168.0.17:12078 and 192.168.0.18:12078. But from an external source if I forward myrouterip:12078 to 192.168.0.17:12078 is there any way I can also access 192.168.0.18:12078 externally?
