my experience is m0n0wall's IPsec components don't stand up well under
poor network conditions (frequent drops, etc.).

can't really suggest much of anything, as my connections have never
had these kind of issues since they tend to be solid (or at least more
solid than described).  Out of curiousity, what are your timeouts?

Just be glad you aren't running a Cisco router site to site VPN.  I
have the misfortune of running a network of those at work.  If a T1
hiccups for just a fraction of a second (making the serial int go down
and up), the router drops its SA's and you have to manually clear the
SA on the other end to get things to reconnect.  I've put my
m0n0wall's through much worse and didn't have to touch them.
