We have a VPN set up between 2 Cisco 501 Pix's. The internet provider at one of our sites changed our static IP address. I updated the IP address on the affected pix, and updated the IP references on the other PIX, but I still can't get the VPN tunnel to re-establish. Here are the configs:
The one that I had to change the IP on:

Is there anything there that I'm missing? I didn't initially configure these, and I'm stumped as to why, after updating the IP's on both sides, I no longer have a connection. Thanks!

You may have to re-enter the command
"isakmp enable outside"
