Not sure if this has been mentioned, but here goes just in case.

I have m0n0 connected to a Cisco router and 2 Netopia routers via 
IPSec.  Since the last beta release I've been having the problem of the 
VPN getting disconnected (for whatever reason, could be timeout, could 
be internet issues), and then never reconnecting unless I reboot the 
m0n0wall, or go into the VPN settings and click "Save".  It then quickly 
reconnects without issue, until it disconnects again.  With version 1.1 
and even the previous beta to 1.2b1 I did not have this problem.  
Nothing has been changed on the other ends for a LONG time.  Just 
thought I'd mention this.  Can supply logs if you want, although they 
don't say much because m0n0 seems to think it's still connected and 
never even tries to reconnect.
