Multiple LAN ports?



  • So after a few days of faffing aroung getting this installed on an old firebox x700, I was wondering if anyone knows how to set up multiple lan ports. I have one WAN configured, 1 LAN and one OPT1, the LAN is connected to my laptop, and it can get connection to the internt but my OPT1 interface can. How do I go about setting it up?

    Many thanks

  • I assume you have just 1 ISP upstream, so just a single real WAN needed.
    OPT1 becomes your 2nd LAN. It should already be assigned to some real NIC on the Firebox.
    Enable OPT1, give it a static IP/CIDR to put it in a different subnet to LAN.
    Enable DHCP on OPT1, give it some range of addresses to use in the OPT1 subnet.
    Put pass rule/s on OPT1 to allow traffic out from OPT1 as you please - e.g. to get going put pass IPv4 all protocols source OPT1net destination any.

    But… if you want to put "opt1" in the same subnet as the LAN, then you will need to bridge the NIC's.
