  • 2 NIC setup, wireless router question

    Hi,

    We have a SBS2003 server with 2 NICs, one connected to a wireless ADSL router and the other to a gigabit switch (and onto the various LAN PCs).

    We've got a few laptops but currently we have a WAP connected to the switch to have wireless access to the network, is there a way to connect to the ADSL router but still see the network?

    Thanks

    Yes, you can have two network cards with different IP subnets and still be able to access both. From the server you'll to setup a route in your routing table for the local IP subnet. This will allow you to access your LAN and route other traffic out of your network via the DSL router - Check out RRAS or ISA 2004 if you have SBS2003 Premium.

    If you want to connect wirelessly to the DSL router, it should have a way for you to configure your local IP scheme to the wireless interface so wireless clients get a LAN IP, local traffic will be routed through the wired interface on the router through to the server, which will need to be configured so the traffic doesn't die there. Again, RRAS or if you're using ISA you'll need to configure it appropriately.

    Have you tried doing this and encountered problems? If so, what happened?

    Are you just asking if it's possible?

      It would pay to have dhcp disabled on the router and have only one server on the network as a dhcp server.

      If you are running two different networks, ie say you have wireless clients set up on 10.1.1.x and wired clients on 10.1.2.x then you can configure dhcp to service both ranges

        The usual requirement for wireless is to give guests some form of Internet access, whilst NOT letting them on your LAN. So wireless clients that you DO want to give access to the LAn can simply set up a VPN connection and you'll hardly notice the difference apart from some name resolving issues (http://companyweb cannot be reached, etc)

          To connect via VPN at the moment we're using our fixed ISP IP (obviously), could/would you connect via VPN on a LAN IP? Or go via the internet?

            If you use the standard SBS set up then your LAN is 192.168.16.0. Now let's assume your wireless router is 192.168.1.1 (which many are, by default), then your SBS External NIC could be 192.168.1.2 - so you would use your MS connectoid to setup a VPN to connect to 192.168.1.2, and upon connection, you would be assigned a 192.168.16.x address by DHCP. Then the station would act like any other LAN connected computer, with the small overhead of PPTP packets.
            TIA
