We´re the following problem between an ASA5540 (7.2.3) Concentrator VPN in HQ and an ASA5510 (7.2.3) in Remote Office:
%ASA-4-402120: IPSEC: Received an ESP packet (SPI= 0xB8EE870D, sequence number= 0x534B0) from x.x.x.x (user= x.x.x.x) to x.x.x.x that failed authentication.
Is established the tunnel and works, but we lost a lot off of packets by is drop en Remote ASA.
The tunnel is type Lan-to-Lan. We have more vpn tunnel in the concentrator 5540 without this problem.
You have any suggestion?
Thanks in advanced.
