Not sure if this helps at all, but I did some searching a bit to read others comments concerning the NAT-T / IPR debate. These two documents get mentioned repeatedly and would appear to have something to do with other vendors decision to adopt NAT-T support. http://www.ietf.org/ietf/IPR/MICROSOFT-NAT-Traversal.txt http://www.ietf.org/ietf/IPR/SSH-NAT There was also some mention of a third claim but it was hard to find details on the subject. Lastly, some people voiced concerns regarding the application of NAT-T to IKEv2 as the first of the two disclosures mention the IKEv1 RFC specifically where the other is quite broad. I can't imagine anyone is actively defending any patent claims here with so many implementations of IKE / NAT-T out there. Would a group such as the FreeBSD Foundation be able to help find answers to legal questions such as this? reference : www.google.com -> nat-t patent ipsec -Matthew
