    Dual Network Cards

    Locked

    by fivemajors ·

    I have a windows 2000 server. Currently I have two network cards. One has an outside IP going through a dsl bridge. The other has an internal ip for the private network. I setup dhcp and routing and was able to hit the outside from a workstationwith a private address. I had a firewall that I was using solely for the purpose of logging, no port blocking at all. I unistalled it and rebooted the machine. Now the server can no longer see the outside. If I uninstall and reinstall the NIC’sthrough device manager I can see the outside when I set the public static ip on one of the cards. As soon as I assigned the private ip to the other card I lose outside connection. I then have to uninstall and reinstall to get the outside again. Iuninstalled the cards and removed them manually through the registry and it still happens.

    Has anyone come across this before?

    I am open to any suggestions.

      If it was working before you uninstalled the firewall, try reinstalling the firewall and see what happens. There may be some files remaining from the firewall that are causing problems.

      The first thing you should check is the TCP/IP settings. The Internal NIC should not have a default gateway nor dns servers. The loopback adapter (127.0.0.1) will be filled in as the primary dns server if DNS was set up on this server.

      If the External gateway setting are in the internal LAN adapter as well then the server won’t route external requests properly. It’s kind of a common issue on Proxy servers.

      Hope this helps.

        This worked, the first time I set it up I had the internal card pointing to itself as the gateway, and put in the external ip’s, I used to the other card, as DNS. For some reason it worked. This time I did as you said and took out the gateway and DNS entries out and I am now back in business.

        Thank you.
