Hi everybody,
this is my first post in this ML; first of all I apologize for my not very
bright english. I've set up a VPN Server with Openswan 2.3.1 with NAT-T patch
and (almost) everything works. Connection starts and I can work in VPN but
after some hours (very often between 296,297 minutes) after connection has
started communication falls and these are the message I see...
