I am seeing similar issues with my 5510. I have 2 lan-to-lan tunnels and multiple users connected via ipsec.

Twice today, I've had to issue the following to drop my lan-to-lan to get it re-established:

clear crypto ipsec sa peer

It's getting a little annoying, but it looks like I may have to update my ASA from 7.0(6) and the DM.

Now I have a question: To go from 7.0 to 7.2, do I have to go to 7.1 first?

No not required, you can directly upgrade from 7.0 to 7.2

HTH if it does.

I have no clue what HTH stands for but if you didn't already figure out you can go directly from 7.0 to 7.2.

NOTE: You will want to look at interim releases for 7.2. I believe 7.2(19) is the latest one. There are several security related vulns that have been fixed since 7.2

You have probably solved the problem already, so I may be too late with this suggestion:

One of my customers had a similar issue which we were able to resolve by hard setting the ethernet interfaces to 100Mbps and half duplex. It seems the ASA does not always auto-negotiate correctly causing the links to become flakey.

Hope this helps (HTH). Mon, 07/30/2007 - 01:06
