<pre wrap="">I have a static tunnel which connects a home network to a company
network. The tunnel works in both directions the way it should. Now the
problem is that after some time of not being used ( for example over
night ) the tunnel suddenly goes down. This means the tunnel is reported
to be up put no ping goes through from the home network to the company
network. Once I send a ping from the company network over to the home
network the tunnel is again open in both directions.
Anybody knows what could cause such a problem?

If you are doing NAT-Traversal, your NAT router might be timing out the
port mapping.

No, this should not be the case. I have the following setup:<br>
<br>
company/home ( both the same ):<br>
- ADSL router set to forward all connections to the server ( hence a
1:1 mapping sort of )<br>
- Gentoo server with OpenSwan with iptables set to not masquerade the
VPN traffic<br>
<br>
This should not trigger NAT in any way I think.<br>

If both end support DPD, you can enable that.

What is DPD in OpenSwan?<br>
