[Openswan Users] tunnel open, but tcp 443 stops working

[John Stile]

Right after I initiate the tunnel, the right can access the left on
tcp443 and ping (ICMP).  After some amount of time, the right can't ping
or access tcp443, but ipsec logs on both SGs show IKE communications
between the security gate ways, and the tunnel appears to be up. If I
send a ping from the left to the right, then the right can again ping
the left, but tcp443 is still not accessible.  

What's going on? 
I don't understand what is causing this.
I need some workaround.

Details about my setup:
left SG:  Debian Sarge, openswan 2.2.0-8, kernel 2.6.8-2-686
right SG: Linksys rv082
