I'm having troubles setting up a site to site VPN with a Cisco ASA5510 VPN server.

Phase 1 is always succesfull no problems there.
Then phase 2 seems to pass too, because we can send and recieve data for a while.
after 30s-7 minutes, the tunnel disconnects, regardless of data being sent at the moment and then phase 2 never builds again unless we reset the connection on both sides.




This part of the oakley log contains the own error message i see, i have a lot more ofcourse leading up to this but i don't see anything strange in that and this'll keep it readable.

On the Cisco side we got this error message earlier:

Anybody got suggestions?
That it even works for a little while seems to indicate ip ranges and subnet masks are setup correctly. But i can't figure out why it won't keep working.

Hi Marc,
Error 13016 means ERROR_IPSEC_TUNNEL_FILTER_EXISTS.
Looks that ASA sends a couple of proposals to ISA for QM. No need for that(configure ASA to send only one proposal matching the one configured on ISA, 3DES, SHA-1, no PFS..). Just a guess though(stupid or not), in order that ISA not to add any default policies...
Also check the Oakley.log to see who "terminates" the tunnel, either ISA or ASA.
Regards!
