Multiple lan segments with 2 nics and no vlans

  • Hello,

    we've an network with 16 lan segments. I plan to install clustered pfsense firewall. I can't install 4 4-ports nics in the servers.
    I can solve the problem by using vlan. but I don't like it.

    Is it possible to implement with only two nics and no vlans? I think I can define the lan subnet in firewall rules… Is it possible and recommended?


  • I assume you want multiple subnets on the same physical layer.
    DO.NOT.DO.THAT (you WILL have major problems with that…)

    Using VLANs or more NIC's is the recommended way.
