  • Problem with using Server 2008 as simple router

    I have the following setup

    One server has two interfaces, one public and one private one.

    The public interface is a 192.168.10.0 /24 network and the private one a 172.168.1.0 /24

    Server 1
    Nic 1 :
    IP : 192.168.10.191
    Mask : /24
    Gateway : 192.168.10.1
    DNS : localhost (local DNS forwards requests to an external DNS server)

    Nic 2 :
    IP : 172.168.1.1
    Mask : /24
    Gateway : n/a
    DNS : localhost

    Server 2 :
    Nic 1 :
    IP : 172.168.1.2
    Mask : /24
    Gateway : 172.168.1.1
    DNS : 172.168.1.1

    I have then added the Routing role to server 1 (2008 Enterprise) and started / configured RRAS with "custom" and "lan routing only".

    What settings do I have to do to "make it work" ?

    I can ping the rras server from the 2nd member server and using nslookup shows that DNS resolution works as well, but there is no internet connectivity.

    Forget the Internet connectivity. Did you check to see if the router functions and passes packets from one interface to the other? Try a traceroute and see.

      It didn't route at all .. but the installation was bust because of someones stupidity (deleted wrong VM) so I had to start from scratch .. that time I installed the NAT option rather than local routing which worked just fine

        Well remember that NAT translates addresses, so perhaps it was just a bad (or non existent) configuration of your routing tables in the first attempt.

          Probably none-existend ... I just started to look into RRAS so I am a bit n00bish with it

            NIC1 looks like it's already NATed. Why can't each device route via 192.168.10.1 rather than going via Server 1?
