<![CDATA[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.

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.

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