Ike Negotiation

Getting the following error "CRYPTO_IKE.NEGOTIATION peer XXXXXXXX: InLength differs from IsakmpHdr field length 260 != 0 !"

Don't know what the other side is. Both sides seem to be configured the same. Don't know why I'm seeing !3DES and DES message as part of main mode 5th message.

Re: Ike Negotiation

Have you tried enabling NAT-T on one or both sides?

On the Netvanta go to IKE Configuration/NAT Translation and set it to "Allow V1" and  "Force V2" to see if this gets you to Quick Mode stage.
