Subject: ASA Site to Site IP Sec tunnel problem

Hi Group

I've decided to go back to my CCIE studies after a few years. Can someone
help me with an ASA problem. I'm trying to build an site to site IPSec
tunnel between 2 ASA connected back to back (using GNS3). I can't seem to
get the tunnel up after trying all day. Below is the config

I have 2 ASAs called ASA2 and ASS3 (sorry asa1 does not exist).
I have an ethernet cable between them acting like my outside WAN:

LAN is 20.0.0.0/24------------*ASA2* (e0/0) 1.0.0.1/24 --------- WAN
-------- *ASA2* (e0/0) 1.0.0.2/24------------LAN is 20.0.0.0/24

asa2# sh crypto isakmp sa
There are no isakmp sas
