  • Subnetting

    I know this has been posted before, but still have somoe questions:
    I need to define 5 subnets like these:

    192.168.1.0/24
    192.168.2.0/24
    192.168.3.0/24
    192.168.4.0/24
    192.168.5.0/24

    Is there a single router can do this? Meaning having at least 5 different RJ45 Ethernet interfaces in a single box, each defining a different subnet? Or I need 5 different routers connected through a switch?
    What kind of router (maker and model) would do that?

    Thanks.

    what is your goal?

    If all this is one building and they are only being tied together for external access (internet for example) I would probably just get a VLAN enabled switch and let it do the work of keeping your subnets seperate

      This is a large network of embedded servers that communicate using UDP messages, broadcasting to address 192.168.1.255, ...2.255, and so on.
      I need to separate them in that way because the way the software we are using works.

        You could do it with a router that has a FastEthernet interface and SubInterfaces for each VLAN. Basically router on a stick.

            Almost any Cisco router can do that.
            Or if you have, you also could use a Layer 3 switch.

              two that come to mind are 3COM 4500 layer 3 switch

              and low cost firewall/router solution might be cisco asa 5505

              both handle vlan's (extra license cost for the cisco)

                you can use a juniper firewall .for example a ssg series with enough ports is a good solution . firewall can do both routing and protecting your network traffic.
