I have a LAN to LAN VPN tunnel established between a Cisco ASA 5505 and a Cisco 2811, but for some reason, I am unable to get SMTP communication between the two LAN's over the tunnel. Do I need to create a specific access rule for SMTP? The 2811's internal IP scheme is 10.4.167.X, and the ASA 5505,'s internal IP scheme is 192.168.1.0. I've attached the running-configs for both the ASA and the 2811. The tunnel establishes successfully, I can maps drives and replicate DNS data without any problems, but canot send email (SMTP) thru the tunnel. Any help would be greatly appreciated.
Did you remove the existing NAT statement before entering the new one? Also,
I noticed that the name of the route-map seems to be different (not
CISCO2811(config-route-map)#match ip address 104
