I'm trying to set up a lan-to-lan VPN between a Cisco ASA 5510 (7.0(5) firmware, IP 222.222.222.222) and a Watchguard X750e firewall (10.2 firmware, IP 111.111.111.111)

Phase 1 comes up but then the message "IKE lost contact with remote peer, deleting connection" comes up in the logs and the ASa never starts Phase 2 configuration. What could be causing this?

Log and config information follows, sorry about the ugly looking wall of text:

From the logs at the ASA end:

And at the Watchguard end:

The config at our end looks like this:

Here is a link to some tips on IKE SA mismatches that may help (also some debug commands to look at covered):

Have you tried disabling DPD ? DPD between different vendors may work so-so... Is -both- devices set to use main mode? Go over settings again and again..

How do you explicitly disable DPD for a connection on an ASA, and how do you explicitly confirm main mode is enabled? –  DrStalker Jul 22 '09 at 23:22
    
Sorry, can't help there, never used ASA, just gave you general IPSec TS info... Google it, saw that there were posts on Experts Exchange about similiar problem. –  Mahriman Jul 23 '09 at 12:12

You have to give a DNS name or an IP address to the gateway ip in phase one.

Put the IP address in and select IP in the dropdown box under it.
