My understanding of what Yogesh said is a little bit different.
Consider the most common case scenario in today's Internet.  People
use IPsec to setup VPN tunnels between their machines and corporate
gateways.  In the scenario considered by TRIGTRAN, one end point of
the tunnel is actually behind the "problematic link."  The router
on the other side of the "problematic link" has no idea what is
going on.
