Because you are sharing the same router and modem it won't work. I'll give you the best explanation I can.
In a normal game, say you set it up. You send out server info through your router and modem to the other gamers, who send you info through your modem, to your router, to your server. In the situation you're describing, it's not possible for one computer. Basically, one computer's upload/download info would have to go out through your router and modem, do a u-turn in cyberspace, and then come back - and that won't happen with a normal game.
The only way you can get both computers sharing a router into the same game is for you to set up a LAN game. Then, the whole situation changes, because a LAN game's dynamics are much different than a net game's. The actual router acts like the internet. One computer recives and sends info as the server through it's ethernet port, and the others recive and send info as the other players.
If you didn't understand that last bit, think about it this way. In a LAN game, your router suddenly becomes the no-mans area between all of the gamers. In a normal net game, the internet is the area between the gamers.
So to answer your question, no, you can't have both in the same game. You'd need to have two different routers, two different modems, and two different ISP connections. Otherwise, you could only play a LAN game.
