Yeah -- totally infuriating again, I need help. My server machine is my laptop with internal IP ending in 6. My client PC is my beefy machine with internal IP ending in 5. Port forward is a nightmare as I have six entries listed (three for out and three for in, including GetMod). All this works when hosting on main client PC but not on another PC on my internal network.
The GetMod ports are pointed to the laptop -- in fact everything is pointed to the laptop now and yet the box is grey-ed out.
