We have set up a VPN between an ASA 5505 and a 1751 router .
That vpn has to replace a previous one between the 1751 and another router .
The VPN is established successfully and I can ping the 1751's internal interface from the ASA's network, but I cannot ping any host behind the 1751 router .
The hosts are fine as they were working before we changed the configuration .
Attached the configuration , I hope some expert can check it and tell me if something wrong.
