Bridging Dual LAN on MSI K8N neo 2 Platinum

I just bought an MSI K8N Neo 2 Platinum mobo, and I plan on using both ethernet ports, but I'd like to bridge them so that I can use one IP address for the computer but still take advantage of the speed from both ports. Is this possible? How would I do it? The WinXP network bridge is already configured, but it's only controlling one LAN connection and the 2 firewire connections. The other LAN connection appears to be independent.

Well, it might be easier to get a gigabit switch ($80?) to increase transfer speed.

can you give me some decent suggestions? I looked into gig routers and cable modems a while back before I bough the board, and noticed that all the "gigabit" routers I looked at all had 10/100 uplink ports...If you're not getting gig speed into the uplink, then how can you be getting gig speed to your computer?

Also, anyone have an answer for me on how i can bridge these two lan plugs so that my computer only needs one IP? I've got port forwarding set up on my router, but I want the ports to be able to come in through both ethernet cables instead of just the one

The term Bridge in Network means Bridging two Independent Networks.

You can not configure two on the same Network to same any Bandwidth Gain using Windows XP and Entry Level Hardware.

It is quite common that people can no let go of this extra piece of silicone that sits on their Mobo, but that is the facts of life.

Why would you need gigibit speed on the uplink?
gigibit speed would only benifit LAN tranfer anyway.

i just used the term bridge because that's what WindowsXP calls that thing in the network connections. It bridges all the network resources into one incoming stream of data. When I had a wireless PCI card installed along with my onboard ethernet, the network bridge combined their traffic so that it was just one IP address for the two incoming signals. I was hoping that was possible with the dual LAN on this mobo.

I think you want load balancing between the cards (both card on one network). A bridge is a transfer point between 2 networks.

What are you doing that you need that much network bandwidth to your computer?

The odds of you needing anything greater than even 10T for uplink are rather low unless it is just to increase the size of a LAN. Simple 100T should do fine, although I had thought that most Gigabit switches had Gigabit uplink. Are you sure you aren't thinking of a 100T switch with Gigabit uplink, which I have seen quite a few of?

just doing some basic p2p transfers and some online gaming, but if I've got 2 ethernet connections, I want to use both of them. Will load balancing allow me to use one IP for the two ports, or will I still need 2 IP's? In either case, how would I load balance between the two?

As my understanding the bridging function in WinXP bridge two networks together so that People in Network A (e.g. through Wireless) can communitcate with people in Network B (e.g. through LAN)

well, i'm not sure, but that's what it did for my wireless card and my lan connection. Anyway, how do I load balance and will it let me use on IP instead of two?

I don't believe what you are thinking about doing is actually possible in the real world. It's simply not how Ethernet works.

Many switches have 10/100 ports and 10/100/1000 for their uplink so when many clients try to send big files they are not bottlenecked by the max 100mbps that the uplink provides

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?

It can not be done two NICs in the same computer can not be configured to be on the same Network.

Any $5 Router can do 10 or more Port Forwarding get your self a new Router

my router can do more than one port forwarding (I have about 20 set up), but they only go to one IP address...If i'm going to have two IP addresses for my computer, I'd like both of them to be able to process anything that my router might block.
