In order to transparently help packet go inside a vpn/tunnel without 
having to solve the security problem of permiting ICMP packet getting 
accross a firewal...

I would like to use "clamp-mss-to-pmtu" inside a bridge (firewall bridge).

It would bridge every traffic, but alter the Maximum Segment of TCP 
connection.

Before attempting this, could anybody give us a hint on the possibility 
for this to work... Was this attempted before (or should I ask for a 
"software patent" on this) :-)

It sound a little bit like what a "Packet Shaper"TM does by altering 
windows size computation.
