Handling two connections with two NIC's on one computer?

post #1 of 10
Thread Starter 
Is it possible to use two connections simultaneously using two network cards on one computer? I am not trying to "combine" both connections to achieve a higher speed (I am relatively sure that is not possible.) Rather, I am wondering if it is possible to assign each connection to handle specified ports.

For instance, I would like first connection to handle streaming on justin.tv, and the second connection to handle Starcraft II.

If this is possible, I'm sure I would need some sort of software, but googling hasn't done much for me. All that shows up are people trying to "combine" two connections into one T_T.

(The reason I have two connections is because I am currently in a dorm and my roommate was not able to afford this semester, so I am here by myself, thank god xD. The connections do not share bandwidth.)

Thanks in advance for any help,

They would just connect you to the same network, AFAIK, giving you faster speeds to anything that is fast enough to saturate Dual Gigabit-which short of a SSD server, isn't going to happen.

No that's not possible to do what you're doing.

If you had two different ISPs and dual NICs (depending what features your NIC supports) you could team them together for more bandwidth.

Teaming is common for server grade NICs...I'm afraid pick either gaming or streaming not both if you network connection can't handle it.

It will increase bandwidth to the local network; LAN not WAN. His gaming performance/videa streaming performance still won't be terrific.

I've only seen NICs get saturated when they're being used for high access databases or SANS.

From what I understand, you are using a university connection that is not limited.
And your dorm has multiple wired lan plugs. And your PC has multiple plugs. And you want to use one plug for certain sites and the other for other sites?

While what your wanting to do (is) possible it' extremely annoying and with your current situation(no throttling), there wouldn't be much point... that I could see.

Yeah, that was what I was getting at.

It can be done - not by port number but by destination IP address. Which could be problematic if your destination has a whole bunch of IP addresses...

Look up the "route" command in Windows...

Thanks to everyone for the very quick responses, however am I not very good with networking so I did not understand some of it .

The connections are each throttled to 1.5mbit/s (192kB/s) both down and up, that's why I thought that doing this would be helpful.

huh interesting, i wonder if you make some type of multiple wan router you'd be able eat up 2+ different connections and chew up all that bandwidth.

Although he could either team both physical NIC's into 1 logical NIC, he wouldn't see any performance increase due to the fact he would need to bind the ports on the back end switch. I doubt he would have access to that switches config. This also would depend on the IOS used as well as the ports each connection utilize for backplane access.
