WAN failover….just a failure - pls help!



  • Hi guys. This is my first post here and as many other, I got here looking for help as I am almost close to give up on pfsense.

    I know it should be easy, but it's not.  :'(

    I have a fairly simple setup: two wans and one LAN. I've read and seen many "tutorials" to no results. I managed to make it work somehow using the following setup but once main in up it does not switch back to it:

    • WAN1(RDS): pppoe gigabit connection
    • WAN2 (UPC): docsis Cisco router 150Mbps, providing DHCP for internal network (192.168.0.0/24)
    • DNS servers: two servers for each GW, each pair for its ISP (see attachment)
    • three gateway groups: Load balancing (tier1 +tier 1 + high latency), WAN1(RDS) failover (packet loss), WAN2(UPC) failover (packet loss). A mention here: If I set the WAN1 Tier1 and WAN2 Tier 2 for WAN1failover (opposed from the screenshots) and by the book, failover its not working at all.
    • Three Firewall rules, one for each gateway group
    • Advanced settings, miscellaneous - Enable default gateway switching ON

    Frankly, dont really need load balancing, I only need failover for the main WAN (RDS, 1Gbps) but all the tutorials instructed to create three GW groups.

    Please see the attachments. Thanks.

    Gents, I am kindly asking you for an opinion on this. Help is highly appreciated.

  • @yanakis:

    what tutorial instruct to create three GW groups? cuss honestly, that just plain bullshit.

    in your situation you only need 1 GW group, the one called "upcfailover" . That one will use the RDS gateway and switch over if it fails. (not sure about your naming skills)

    also: remove the second and third firewall rule on LAN (only anti-lock & upcfailover should remain)

    also: you can probably uncheck default gateway switching, because that would only be required for services running on pfsense itself (like squid)



  • Hi heper.

    I quickly found a couple:

    http://www.tecmint.com/how-to-setup-failover-and-load-balancing-in-pfsense/

    Initially, I tried exactly the way you said below but it did not worked so I had to dig deeper, read more…and things got even more complicated.

    Now, the "new" setup: one GW group, one FW rule, unchecked GW switching, reset states, reboot. Still not working.

    I tried to ping the dns servers assigned to failover GW (UPC) and they reply back.

    I got no other ideas.

    Edit: it seems it switched to failover (UPC) after 10 minutes and now is staying to it although I brought back main Wan (RDS)
