We have created IPSEC VPN tunnel between two Cisco ASA 5510 firewall. After establishing the VPN tunnel, when we are generating the traffic in that tunnel, it is showing up and active but we are unbale to "PING" or access our local LAN segments. I am getting the following syslog error...
1 Nov 10 2008 16:21:22 713900 Group = XX.XX.XX.XX, IP = XX.XX.XX.XX, construct_ipsec_delete(): No SPI to identify Phase 2 SA!
Please note the IOS version of one firewall is Cisco ASA 8.0(4)for another one is Cisco ASA 7.0(7)
Please help me by providing the neccessary solution to overcome this problem.
