Hi, I see the above message in the tcpdump of /var/run/isakmpd.pcap, when a cisco router establishes quick mode to my openbsd. The connect works ok, just wondering what this message could mean. I have only seen 'ENCAPSULATION MODE = TUNNEL' in this context.
As connect setup fails in the opposite direction ( with NO PROPOSAL CHOSEN from cisco ), using the same parameters. regards christoph
