appreciate you taking the time to put together those step by step directions
for me. The install seemed to go fine and when I run IPSEC verify, it
shows that I am now on U2.4.11/K2.6.22-14-server. Unfortunately, my logs
are still showing the same errors as before.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>One thing I thought of was that, when I started this project a
month or so ago, I had a Linksys WRVS4400N at the remote site, same as I do
now, and a Linksys WRV54G VPN router at the HQ side. I was using all the
same IPs that I am now and I was able to create the tunnel no problem. I
decided to do away with the WRV54G because it wouldn’t keep the tunnel up
for more than an hour or so and also I knew it would not handle the throughput
of the 20 or 30 sites I would eventually (hopefully) have up on the VPN.
If I am correct, this means that the IP configuration of all devices involved
should be OK. As you said though, it seems that the packets never get
back to the Linksys. This is very strange.<o:p></o:p></span></p>
