I have a main location with a static IP + ASA 5505, and a second location with a dynamic IP + ASA 5505. I have never done a dynamic tunnel before, so im not sure what i missed. Attached are the scrubbed configs - thx for the help.
Note: There is an IP phone on the Dynamic side that connects to the main office phone system. Now, eventhough the VPN Tunnel is not up, it ONLY works when plugged into the LAN @ the corporate office, OR on the remote network behind the ASA - it will not work from any other internet connection - and im absolutely positive it's connecting via LAN IP and not Public IP, which is strange.

Hi,

you need to add the following:

access-list l2l-vpn extended permit ip 192.168.10.0 255.255.255.0 192.168.20.0 255.255.255.0

crypto map dyn-map 10 match address l2l-vpn

on the other side of the tunnel you need to do the "reverse" implementation (assuming your naming convention on vpn config is mirrored, otherwise change accordingly):

access-list l2l-vpn extended permit ip 192.168.20.0 255.255.255.0 192.168.10.0 255.255.255.0

hope this helps
