Bridge lan connections

  • Hi

    I have 3 Ports on my router (WAN, LAN, OPT1) I want to bridge LAN and OPT1 together to increase LAN bandwidth to the router.

    I have been following this Guide

    The question is how do I test if it worked? In the traffic graphs I do see LAN traffic flowing in both LAN and OPT1.

    Is it safe to assume that it is working? Are they any other tests I can perform?

    I have 3 Ports on my router (WAN, LAN, OPT1) I want to bridge LAN and OPT1 together to increase LAN bandwidth to the router.

    That is NOT bridge, that'd be a LAGG (plus adequate switch required). Not to mention, you seem to have some strange idea how the traffic flows. LAN -> LAN traffic does not normally hit the router at all.

  • Hi let me try to re-explain,
    My setup is I have a pfsense router with 3 gigabit Ethernet ports, they are WAN, LAN and OPT1.
    The WAN connection goes to the modem and the LAN connection goes to the Gigabit switch (OPT1 is free atm).

    I have squid cache running on the pfsense router. When I said I wanted to bridge (maybe the correct term here is NIC teaming or bonding) LAN and OPT1 together to increase LAN bandwidth I meant the transfer speed from the squid cache to the LAN network so if there are multiple computers pulling data from the squid cache (say a large windows update or video file) and exceeding the 1 gigabit speed limit that it would use the speed from the OPT1 connection as well.

    So both the LAN and OPT1 would go to the same gigabit switch thus creating a dual gigabit connection to the pfsense router (which is my goal).

    It would be like having a server which has 2 Ethernet slots, both which are plugged together on the same switch in bridge mode. If 10 computers are pulling data from the server having the 2 Ethernet ports in bridge mode would increase the LAN bandwidth for the other computers from the server.

    Thanks for the help

    No, once again, that would not work. Bridge does NOT aggregate bandwidth.

  • Does pfsense support aggregate bandwidth?

    Already told you that you need LAGG with proper switch.

  • Ok thanks going to see if it will work with my hardware

  • I am having a little trouble with migrating LAN to LAGG (with LAGG I am temporary using failover mode in a view to use lacp)
    When it comes to the step where “Navigate to Interfaces > (assign), change the assignment of LAN to the newly created LAGG interface (LAGG0)” (so it would look like this under Interfaces: Assign network ports Interface = LAN, Network port = LAGG0) after this step is done I lose network connection and have to Restore recent configuration from the serial connection.
    Any ideas?

  • Did you really add only the third, spare interface to LAGG, test function with appropriate configured switch and add second IF after that?


    Create a new LAGG including only the second NIC

  • Hi, It looks like my gigabit switch does not support link aggregation, might have to try later when I get a new switch that supports this feature.

    Thanks for the help


    Thinking maybe the TP-LINK TL-SG108E?

  • I don't know that one but have worked with TL-SG3210 successfully in the past.
