Re: [Users] Windows Timeout => IPSEC SA

You can apply Mathieu Lafon's Notification/Delete SA Patch
available from

   http://open-source.arkoon.net/

to FreeS/WAN. W2k unfortunately deletes an IPsec SA after
about 6 minutes of inactivity but it sends a Delete Notification
before the connection goes down. With the patch installed
FreeS/WAN will delete its side of the connection, too.

If you want the connection to be up all the time, configure
a WINS server in the subnet behind the FreeS/WAN gateway
and point W2k on the roadwarrior to it. This will produce
so much verbose traffic that the connection will never go down ;-)
