VPN issues Cisco to Sonicwall

padred123 · ‎07-28-2016

Hi, I have a cisco 1841 that I am trying to connect by vpn to a sonicwall. I do not have access to the sonicwall and I am trying to determine if the issue is on my end(cisco). I've read that Cisco ASA's need PFS enabled on the sonicwall but I'm not sure if it does for 1841's as well. Any pointers will be greatly appreciated.

Peer: xx.xx.xx.xx

Local: YY.YY.YY.YY

I get the following error:

%CRYPTO-6-IKMP_NOT_ENCRYPTED: IKE packet from xx.xx.xx.xx was not encrypted and it should've been.

sh crypto isakmp sa

CRC_1841#sh crypto isakmp sa
dst src state conn-id slot status
XX.XX.XX.XX     YY.YY.YY.YY   MM_NO_STATE       1140    0 ACTIVE (deleted)

Your side seems reasonably happy. You need to ask the other end why it is complaining.
