HOWTO: set up a VPN connection between a RVS4000 on a dynamic IP and an ASA5510(8.2) on a static IP

Whenever I try to do this, I get a slew of messages in the form:

Apr 21 15:13:41 [IKEv1]: Group = #, IP = #, Header invalid (next payload = 11)

from the ASA.  The RVS4000 is equally unhelpful.

I've made sure they have appropriate Phase 1 settings, and even reset the pre-shared key to "test" to make sure it wasn't typoed.

If anyone else has tried and succeeded with this, can they give me something step-by-step on how to set this up?

A little more data and/or screenshots would be helpful.

Take a look at the log files on the RVS router. I bet you may see a section where the negotiation begins and the output is just a bunch of hex.

There are a couple of things to note. One make sure your pre-shared key is at least 8 characters long. Two do not use PFS unless you have gotten this to work in the past. At this point I would just recommend deleting the tunnel on the RVS and setting it up again, but this time use a different name and make sure your pre-shared key is longer than 8 characters.

If this still fails please post logs, screenshots or anything else you may feel helpful.
