I'm not sure of the specific rule(s) atm, but there is something that 
shorewall does that breaks the vpn.  On my last generation of routers, I 
have to make sure to restart ipsec after I restart shorewall or I loose 
my connections.  Sadly, shorewall creates a lot of rules, most of which 
I don't understand and I've never taken the time to analyze the 
problem.  I just got in the habit of doing this if I have to restart the 
firewall:

shorewall restart && ipsec setup restart
