Error 412 whilst using ASA5520 for VPN

Hi

Hope somebody can help. I'm trying to use a new ASA 5520 to terminate my remote access VPN's. The remote clients use the cisco VPN client V5. I'm using the configuration below and testing using a laptop directly connected into the same VLAN as the outside interface. I can ping the outside interface, but when I try to connect using the client I get Error 412: Peer not responding. Debugging ISAKMP on the ASA shows no attempt to connect. The laptop will connect to our existing VPN without a problem.

Does anyone have any ideas that may help me out.

Many Thanks

Rob

We have the same Problem with VPN-Client V5. But the Version 4.8 ist OK.

The only difference between this two Versions is, that V4.8 uses Port 500 as Source Port and V5 uses Port 1501 as Source Port. Both Versions uses the same pcf-File.

I have captured the packets and this was the only difference in both Packets.

But I don't know, how I can fix this Problem.

Do you get a solution since your posting?
