I was wondering how long this would take for an ATX PM board, AOPEN gives us this little wonder. Though it will cost you, between $248-307 apparently http://www.theinquirer.net/?article=24476
Firewall - Have one NIC connected directly to the modem, the other to the network hub/router. That way no-one from the outside gets to the network without physically going through the firewall first. Router - Connect two networks together via one computer which has an IP address for both networks. That allows you to develop two separate networks that can still communicate to each other without having to be all part of the same network. Server - A high-load server could have two separate IP addresses on the same network, increases its bandwidth. Dual-connection speed - Theoretically it's possible for two computers both with two NIC's installed to communicate to each other on both cards simultaneously, I saw a How-To on that recently but damned if I can remember which one. Does that answer your question?
Yea that's why gaming boards come with 2 NIC's because then if you are having a LAN game (no internet is fast enough to make it worthwhile) then you can get 20/200/2000 enet connections. Also I have an old Sony Vaio with 2 NIC's that I am running as a firewall. You can do it using Linux. Mandrake I know can but there are distros such as Smoothwall (the one I use) and Monowall that are specifically made to be a firewall/router.
The PS3 for some reason has 3 network ethernet ports at the back. 2 for input and 2 for output I think.
Hahahaha, that should go in the corny jokes thread zRock. But, no game will need 400/4000 Mbps connections in the next at absolute least 10 years, especially a console game. I wonder if thats actually true or if it's a product of the rumor mill. It would make sense to have like, a phone and 2 enets, maybe.
