  • Router to seperate lan network

    Hi All

    Can someone advise on some devices(make & model) which can be used to join two subnets, E.G Servers are on 192.168.1.x Class C Subnet and the work stations are on another subnet 192.168.40.X Class C Subnet.

    I'm basically looking for some router/firewall/switch device.

    Regards

    You need a router that supports inter-vlan routing. Could also use a layer 3 switch to accomplish the same thing.

    As far as makes/models, most business class devices will have this functionality.

      Surely he just needs a router, as by definition a router is a bridge between subnets?

        Hello Mark,

        Depending on your needs you can accomplish this with a server configured with 2 NICs (either running routing services, or just IP forwarding between the two NICs). While that would not be my first choice, what you ultimately use to route between the two subnets depends on exactly what your requirements are. In your post you mentioned that you need the router to include firewall services.

        If this is for a production network, you may want to look at some of the smaller, intro boxes from the following vendors: Cisco, SonicWall, Checkpoint, Palo Alto and Juniper to to name a few. You would be looking to spend a few thousand dollars.

        If this is over your budget, you may be able to find a less costly consumer based router that meets your needs.

          If the router supports Switched Virtual Interfaces then he could do it on one box. If not you could take a router (Cisco) with 2 ethernet interfaces and create subinterfaces on one of those for your lan subnets then trunk to a switch that supports vlans. Basically a "Router on a Stick configuration". Better option would be a L3 switch for the intervlan routing portion. You can pick up a used 3550 for about 200.00 these days.

            If budget is a concern then using Linux or BSD might be a good option. There are also some free turnkey Linux firewall products like Untangle. Astaro has a free home version of their software and they might have a free business version... not sure.
