We have ISP router> hq 2821 perimeter router>ASA5510 firewall. The firewall creates and breaks IPSEC tunnels. Cisco VPN Client was downloaded and installed on computers. The computers can ping outside interface of the ASA firewall, but can not create IPSEC tunnel. Any suggestion would help in troubleshooting.
The following link has information on most common remote access VPN troubleshooting solutions. Give it a try and let us know if you are still having problems. Posting a sanitized copy of the ASA configuration would help.
I downloaded and installed Cisco VPN 5.0.02.0090. I can not create a tunnel. Could you advise. The following attachment contains the sh ru output. Thanks.
