Hi All,
I’ve seen similar posts to this problem and I still haven’t managed to crack it so I thought I’d try my own post. I have a VPN client running on a laptop connected a DSL circuit. The VPN client is configured correctly for an external address on another firewall, this external firewall passes through ISAKMP / IPSEC to an ASA where it terminates. The client authenticates and gets an address from the client pool (VPNCLIENTS – 10.2.16.x / 24) and the tunnel completes with no problems. From the internal ASA I can ping any internal network behind the 10.0.3.240 interface (INSIDE) and I have a route on the inside network to get to the 10.2.16/0 clients to point to this address (10.0.3.240). All good so far.
Now the problems begin. I cant ping anything from the VPN clients (10.2.16.0) network to anywhere, I cant ping any interface on the ASA or any internal network. I also cant ping the client from the ASA and therefore not from the internal network either. This configuration is bare bones configuration so I don’t even have the NAT exception rules added. Looking for advice to get this to work. Network diagram attached too.
