Thank you for the reply,
the rekeying duration issue has been solved but the main problem still remains. About every 23 minutes the tunnel gets reconnected.
How can i figure out, what the reason for this (User request seems not adequate)
Here is a fresh log :

On IPSec negotiation, the rekey is based on lifetime or bytes. when negotiation
takes place, the lowest value is always used. So it does not matter if one is
higher than the other, the negotiation does not have to agree on the
lifetime/byte values.
Are you running IPSec VPN with udp encapsulation?
I have seen problems with them, because some SOHO firewalls like netgear etc,
treat them as UDP connections and closes the state after a predetermined amount
of time.
The way that you can see is if you run tcpdump/ethereal you will see heck a lot
of UDP packets going between the client and the VPN concentrator.
If that is the case, two ways to fix it:
1. Disable SPI on the SOHO router/firewall (very bad, not recommended)
2. Disable UDP encapsulation and enable ESP to flow, i.e you will see protocol
50 for the IP header, instead of protocol 17, all newer routers/firewalls allow
them through.
Can you forward crypto config from the Cisco VPN concentrator?
Hope this helps.
