Hi!

Thanks Bob for your points!

To clarify the symptoms on my machine: It is only the routing entry that 
disappears, the IP address remains active. The lease should not be the 
problem, as the duration is 30 days or the like..

The only related message i see is this:

in.routed[1174]: [ID 559541 daemon.warning] 0.0.0.0 --> 192.168.2.1 
disappeared from kernel
