I'm running a VPN server using an 1841 with Adv. Security on it. VPN is working fine once users are connected (using Cisco VPN client). But I'm always getting that message: %CRYPTO-4-RECVD_PKT_MAC_ERR: decrypt: mac verify failed for connection id=3003 local=192.168.22.12 remote=21.101.43.28 spi=D9D865B6 seqno=000025E5


Of course the remote IP depends on the client that is connecting. But I can't fine any way of getting rid of those messages and they are filling my syslog each time a users connects.


Any idea ?

It's a known issue but is only cosmetic. You can ignore or if you recently upgraded the IOS, downgrade.
