we have the following problem: Client to Site VPN is dropping
connections, especially, when using pcanywhere or Terminal Server
connections. When using rconsole to different Servers behind the
BM3.6, everything is working ok.

When using pcanywhere, it works sometimes very good, but then, it
kicks the "session", and a new vpn connect has to be startet (although
vpn monitor shows that the connection is still ok).

Not sure, whether this could be a packet size problem, the packet size
for the pcanywhere workstation was reduced to 1300 bytes already...
