Have OPT1 and OPT2 behave like additional LAN ports?

  • My pfSense box and cable modem are in my living room, with a HTPC and Ubiquiti UniFi AP next to them. Then the rest of my computers and servers are way on the other side of the house, requiring nearly all ports of a 24-port switch.

    Normally I guess I'd have to plug a small switch into the pfsense LAN port, then plug the HTPC and AP into that switch, and also run a cable from said switch to the 24-port switch. That's simple and all, but I don't have a spare switch, but I do have a spare 2x gigabit NIC.

    I plugged the extra NIC into the pfsense box and setup interfaces OPT1 and OPT2. However when I plugged the HTPC and AP into these interfaces, they couldn't access anything.

    What's the trick to getting OPT1 and OPT2 to behave like additional LAN ports?

    :) search is your friend

    You need to bridge the ports.

    Go buy a switch dude..  Much cleaner solution than bridging..

  • You have a couple of options. What you have done will technically work, you will simply have them on different subnets and will need to configure things appropriately and enable firewall rules to pass traffic between the interfaces. You will essentially be doing Layer 3 routing through it and depending on the specs it may not be up to snuff to handle full bandwidth if you want to push large files to the HTPC.

    The other option is to get a small switch and put the firewall, AP, HTPC and uplink to other switch on it.

    You could try bridging the interfaces but I honestly have no experience with that option and can't help you there. Honestly I think option 2 is your best bet or option 1 if you can't get a small switch there.
