I have a CISCO ASA 5505 Ver 7.2(2). I have done a VPN with a Cisco3000 VPN Concentrator. The Vpn is up and I can ping all the remote hosts that I want, but if I ask something else (like a ftp or http connection) the internal network stop to respond me and i can't see anythings. I see that the VPN remain up and to bring up the internal network i must ping the internal host from the ASA. This firewall does only this work.
Have you any idea why it happens?
