After setting up an L2L VPN between an ASA 5505 and Cisco 3825, I'm not able to ping the inside network.
My network for the ASA is 172.28.45.0/24 and for the 3825 is 172.28.53.0/24. I've been told that there may be overlapping in the ACL and all.
But when I change the 3825 network to 188.8.131.52/24 the VPN is not up at all. Attached are my configs, please help on both issues as I ould like to have the 172.28.53.0 and other network VPN also to be up.
Your inside network definitions were fine, don't change them if they correctly represent your network configuration.
From the output you provided it looks like you are pinging the inside interface of the 3825 from the outside interface of the ASA. The outside interface of the ASA is not in the encryption domain.
Try pinging from another device on the 184.108.40.206/24 subnet to the 3825 interface or to another device on the 171 28.53.0/24 subnet. That will generate "interesting traffic", traffic defined by the encryption domain.
