Multiple interfaces seeing each other



  • Hi all

    I have 3 interfaces total - WAN, LAN1, and LAN2.
    LAN1 is my main interface and LAN2 is basically a 10GB NIC plugged into my server's 10GB nic.
    I would like to be able to access my server from computers on LAN1.

    What would be the best way to do this? Create a bridge? Setup 2 different subnets (192.168.0.1 and 192.168.1.1) and create rules for them to pass traffic to each other? Not sure if those are even a correct solution to my problem..

    Looking for some professional opinions :D
    Thanks!

    You almost never want to create a bridge.
    Give LAN2 a different subnet as you already said, add Firewall Rules to allow traffic and let it flow. ☺

    Thank so much!

    To allow traffic, do I need to make a rule on each interface?
    So on Lan1 interface allow Lan2 traffic to Lan1 net, and on Lan2 interface allow Lan1 traffic to Lan2 net?

    Does that make sense?

    With the Default allow LAN to any rule on LAN1 you have the traffic already flowing from LAN1 -> LAN2
    Now it depends on what you want to do. ☺ If you just want any device can access any device add the same Rule on your LAN2.

    Depending on what you run on this Server, maybe building a DMZ would be a good option for you...now when you have two subnets anyway. ☺
    There is a GREAT hangout done by jimp on Creating a DMZ: https://www.netgate.com/resources/videos/creating-a-dmz-on-pfsense.html
