[Openswan Users] cisco and timeouts

[jef peeraer]

i've got a cisco setup, at the roadwarriors site, and it seems to work 
with my openswan server ( 2.4.5 ). there is only one thing ( kind of 
blocking ), after a certain timeout, the tunnels seems to be closed. on 
the wiki , there seems to be an article about this, but the link is dead.
i feel it has something to do with a statefull firewall and timeouts, 
but my cisco knowledge is very limited ( did the basic setup via the web 
interface ).
my cisco config is as follows

no service pad
service timestamps debug uptime
service timestamps log uptime
