Help w/multi interface communication behind wan

  • I'm new to pfsense, so any help would be greatly appreciated.

    3 nics, 1=wan, 1=lan, 1=opt

    lan = connected to switch
    opt = connected to switch

    lan and opt interfaces are set to static w/dhcp enabled
    lan interface =
    opt interface =

    rules are * for lan and opt interfaces

    Gateway settings set to none and internet works on both networks.  dhcp works great on both.

    The issue i am experiencing is that there is no communication between the networks.

    Am I missing something small or large here?  Any help would be greatly appreciated!

  • Screenshots of of lan and opt interfaces would be great. But for mean time do you want that pfsense act's like a router between, so it don't nat between two local interfaces?
    if so, you'd have to change nat type to manual (Firewall: NAT: Outbound)

    1. go to NAT section
    2. select manual and click save
    3. add new NAT rule
    DO not NAT = Check this
    Interface= LAN
    Protocol = Any
    Source = Network, put OPT subnet here
    Source port = leave it empty
    Destination =Network, put LAN subnet here
    Destination port = leave it empty
    Leave others empty
    Description: opt-2-lan or something descripive

    And after that create another rule which is almost the same, change Interface OPT and source and destination switch places

    Finalizing touches, move this new rules at the top of the list and save/apply changes. now it should work. (I hope I didn't mess up with interfaces badly)
