The machine has two NIC's, each connecting to a separate network.

  • Network A is Internet facing and requires a proxy to do so
  • Network B is an Intranet

The problem is, if I set the proxy settings, I cannot access sites on Network B. If I don't set them, I cannot access the Internet (on Network A). Is there a way to set this up so I don't have to keep flipping this setting on and off?

The specific browser I'm using is Firefox, but I'm asking in more of a general sense. Is this something I could configure on the NIC itself?

You can't do it per NIC, but you should be able to do it per address range. Look under Options, Advanced, Network, Connection, Settings, No proxy for.

I don't know how I've never seen that before, it was right in front of me! I guess I just wasn't entirely sure what I was looking for. Thanks! –  Gary Jun 14 '11 at 14:22
    
I do have one follow up question. This option allows me to enter a domain name or IP range. I don't suppose there's a way to do so for NetBIOS names (within that IP range) other than manually putting in each server, is there? –  Gary Jun 14 '11 at 14:27

Most browsers have a proxy exclude list.

Add your intranet to the exclude list and use the proxy for everything else.
