I recent;y had an issue at my data centre and now the VPN remote clients can no longer connect to my VPN Concentrator.
Cisco 3000 series
Cisco VPN Client 4.02D

Getting these errors on the client logs:

9 20:40:48.693 05/24/08 Sev=Warning/2 IPSEC/0x6370001E
Unexpected TCP control packet received from x.y.108.108, src port 10000, dst port 2339, flags 14¿B

L2L sessions work OK though. I am wondering where the error is happening. Something in my AAA server maybe?

Help!!! The non techie in the data centre troubleshooting Cisco!
