Hello

Sorry for my poor english

Does anybody know or have information about this error log or the cause for this issue or in what side is the problem (Source or destination)?

172.16.70.10 (Source)

10.24.1.26 (Destination)

IPSEC(sw_esp_decap): fail antireplay check

IPSEC(cipher_ipsec_request): decap failed for 10.24.1.26 -> 172.16.70.10

sometimes the people that are using the VPN tunnel lost conectivity, and when i check the Tunnel, it is up.

i use these debug commands: debug crypto isakmp and debug crypto ipsec

and i got this log and i could see with the command sh crypto ipsec sa that the counter in receiving errors were incremented
