[Openswan Users] OpenSwan + L2TP + network outage

[Danilo Godec]

 Hi,

we have a couple of home users using L2TP VPN to access work stuff.
Sometimes they have some transient network problems / outages, just long
enough for Windows to 'close' the connection...

However, the server (SLES 10 SP2 with OpenSwan 2.4.6) doesn't detect
that and the connection seems to be 'up' for a long time - so users
cannot reconnect...

Is there a way to solve this or at least shorten the time needed for
OpenSwan to drop the connection?
