Replay Attack

Hi All,

I see the replay attack warning and the VPN dropped.

Warning: possible replay attack. Sequence Number 1156 (Expected 1212)

I see the default replay window size is 64, if that is the case the above packet should have been allowed right? 1156+64 = 1220 and the expected packet is 1212 which is less than the window size. What could be the reason for the above issue?

Any suggestions is highly appreciated.

Regards,

Sanjay S
