WAN flapping



  • I am using a failover setup as per the instructions on the Wiki and after reading every post to do with multi WAN here, but I still have a simple problem that I cannot work out.

    When I use bittorrent (and only when I use bittorrent) WAN goes up and down constantly. Bittorrent does not even notice, but pfsense sends the link down but then never fails over.

    I would like some idea on what is going on here. 203.xxx.xxx.xxx is my ISP DNS server.

  • Upgrade to 1.2.1
    If you search with keyword = Service changed status, reloading filter policy
    There are some hints like changing Monitor IP



  • Thanks for your reply Perry.

    I have changed the monitor IP address from my ISP DNS servers to OpenDNS Servers. Its not the monitor IP address.

    Thanks for the idea on updating to 1.2.1.
