Trying to configure a S2S VPN with Cisco ASA but keep getting errors on the Adtran:
CRYPTO_IKE.NEGOTIATION peer 75.77.31.48: InLength differs from IsakmpHdr field length 1368 !=
Looked all around and have not found an answer.
Thank you for asking this question in the support community. When you get a chance, will you reply and attach a current copy of the ADTRAN unit's configuration? Also, it might be beneficial if you could reply with the output from the debug crypto ike command, so I could assist you with reviewing the VPN negotiation.
Please, do not hesitate to reply with any additional information or questions. I will be happy to help in any way I can.
