PfSense MultiWan fails every second connection

  • I have successfully deployed several pfSense ALIX and WRAP boards. Now I have a problem getting MultiWan to work. Every second connection doesnt reach its destination. Here's the outline of my network:

    DSL, directly on WAN Interface
    Router IP Subnet <– Netgear Router, pfSense as DMZ on IP

    What should I set as gateway for firewall rule number one? I've set up everything according to the pfsense multiwan howto for 1.2 and I'm using pfSense 1.22.
    No static routes defined. Do I need any because of using PPPoE on the WAN interface?  I couldnt find anything appropiate on the forum. I've even set up a static route for the monitor IP on OPT1, but that doesnt change a thing.
    The rule was:
    Interface  Network  Gateway  Description 

    Firewall rules:
    Proto  Source  Port  Destination  Port  Gateway  Schedule  Description

    • LAN net * WAN address * *   Make sure WAN traffic goes to right interface
    • LAN net * OPT1 net *   Make sure OPT1 traffic goes to right interface
    • LAN net * * * LoadBalance   Everything else gets shared out

    The system log shows these events periodically:

    System log:
    Jan 30 14:17:09 kernel: arpresolve: can't allocate route for
    Jan 30 14:17:09 kernel: arplookup failed: host is not on local network

    Furthermore, failover detection doesnt work.
    This is my loadbalancer setup:
    Name  Type  Servers/Gateways  Port  Monitor  Description

    LoadBalance gateway wan
    (balance) opt1 Round Robin load balancing

    WAN1FailsToWAN2 gateway opt1
    (failover) wan WAN 2 preferred when WAN 1 fails

    WAN2FailsToWan1 gateway wan
    (failover) opt1 WAN 1 preferred when WAN 2 fails

    Even if I disconnect the modem on, the link remains UP. Might be because of the system log error?

    Any help would be appreciated.
    Maybe I'll try to use an additional router on the WAN Interface and switch the WAN interface to static IP. I dont know anything else I could try...

    sincerely, localhost

  • thanks, I'll check it out.

  • Thank you,
    been having a hard time setting up
    this multi wan on 1.2.2.

    and the multiwan howto didn't work for me either.
