hmm...not exactly what I was looking for. Just to make sure that no one is misunderstanding me, let me reiterate
I have one cable internet connection coming into my house which goes through my cable modem to my 4 port router. My router then manages 2 computers: mine and my roommate's. I just bought a new mobo with 2 ethernet connections on the backplate (MSI K8n Neo 2 platinum), so my router has one ethernet cable going to my roommate's computer, and 2 cables coming to mine. I have port forwarding set up to one IP address because that's all that my router can do. Is there a way to "combine" the two connections at my end so the router thinks that both of the cables are going to the same IP address?
It's sounding like that's a no, but i just wanted to get a straight answer before i gave up...also, if it is a no, how can I reliably use both ethernet connections? I have programs that require port forwarding. How can I be assured they won't just switch which thernet port they use? Do I now have to instruct all my programs which port to use? If so, how do I do that?
