Two NICS in a PC

Hola:

We have set up a new PC to host a Novex2000 surveillance system (four cameras). The PC has a nic connected to a router, in order to serve a remote viewing module (got it at home). We want the pc, as well, to be connected to our LAN, so we installed another nic. My question is how can I instruct IExplorer to use the second nic to access internet, as we want the router to use all its bandwith to send video?
We have setup the router for the video signal as mono (no nat), and the nic uses its wan IP (80.59....).The lan nic uses the 192.168..... range.

Thanks

Well see - you open up Internet Explorer
Tools->Options
Click on Connections
remove all the ones that are there
Click Add
choose the 2nd NIC

I'm puzzled why you have 2x NICs....as if you have a router, and you want to have a LAN....all you do is use the built in 4 port switch on the router, or uplink the router to another switch that your LAN is connected to.

Anyways, the NIC you want to use for the internet, you put the gateway in that TCP property.

However...some applications aren't always multi-homed friendly.

So lets look and see if we can get a single NIC approach going...based on more details from you about your overall setup.

Gort9k,

The easiest way to solve your problem, is to build a static routing table, pointing only traffic destined for the security network or server out of the one gateway (nic), and then make the other interface your default gateway or default static route.

If you need help configuring static routing let us know.

Thanks for your answers. I haven't been at my office for a couple of days, so I have not tried your hints.

The reason for the second router is that (having in mind that Internet is not a very fast way to send images) we want one (router) to be dedicated to this labour. For this reasoning we installed a second nic, to connect it to the new router and isolate it form the lan traffic.

Bear in mind that I'm not a computer technician, and so, I can do some things that you think I am completely crazy. I beg you to be patient

Gracias

Greetings!
I did just what you are describing, But with only one Router, two NICS, and a security system. (An Xbox and a FTP server, and a few other PCs.)

I have a D-Link DI524, so I also have a few laptops that I can conntect to any other system on the LAN with.

I had the router get the IP from the DHCP server with my ISP. (Automatically happens.) Then I set up NIC 1's properties, and assigned a dynamic IP to it. I found the same card's MAC address in the router, and set it to always assign the same IP to NIC 1.

I left NIC 2's properties alone, in its own settings, and with the router.

Any local traffic gets sent thru NIC 1, via the router. As well as incoming FTP requests, and security systems settings (via admin login) from the internet. (Specific IP range only so that I can access/check it from work).

All of my outbound internet goes thru NIC 2.

I know this all sounds complicated, but it's not really. If you have any questions, feel free to ask.

Hola:

What a week! not a free day. Travelling from one island to another (for those who care I live in the Canary Islands).
Well today I had some spare time, so I went to work in this two nics bussines. After donig some crazy things, like deinstalling and reinstalling those blasted nics, I got achieved what I wanted. One nic works for the router, sending and receiving data from local and remote cameras, and the other nic handles the internet traffic.
One thing is to have everything working and another one, very different, is understanding HOW it works.
My question is: how can I instruct IE to use a nic instead the other one?
If I go to IExplorer-Tools-Internet options-Connections-Lan. I can not see any option to point IE traffic to a nic.
