I have a L2L vpn between a Cisco VXR7206 and a Checkpoint firewall. Everything has been running great for almost three years without any issues. Nothing has been changed by either sides for the past three years.
For the past three days, i have been getting a lot messages like this below:
vpnIOS 270430: 136228: Apr 23 22:01:06.717: %VPN_HW-4-PACKET_ERROR: slot: 2 Packet Encryption/Decryption error, Output Authentication error
Anyone know what this message mean and how to go about fixing this? Thanks in advance.
