If it could be as simple as that. But, as I written in my previous e-mail,
the ISDN connection is made through an external router, not through an
internal card ...

Perhaps I didn't explain my problem very well, sorry about this :(

The firewall never knows when the line is up or not. The line just goes up
when a packet is sent to any external address ... So cipe is always up and
I'd like it to be kept in this state as otherwise it would require a manual
user action to bring it down then back up again. This is what I'd like to
avoid. Currently users have to bring it down and up every 30 minutes, they're
firing me about this ;-)

The problem here is it seems cipe can't resync itself after a long period of
inactivity. Solution would involve regular cipe pings, but this would have
the side effect of keeping the ISDN line up everytime.
