Link loss can cause multi-WAN difficulties
When you lose link on a NIC assigned as an OPT WAN, the static route that directs the monitor IP out the correct WAN may get dropped from the routing table, causing the monitor pings to follow the default gateway. Generally not an issue as a WAN failure rarely results in link failure, but something we need to address in 2.0.

This needs more testing, and possibly a different solution, depending on how the routing functions in FreeBSD 8 and what unknown fallout there may be.
The code in filter.inc needs to be updated to never add a gateway on an interface that doesn't have link to help with this scenario.
