Oi, indeed exactly the same problem. I must have missed your post, else a "me
too!" would have sufficed. You're also using 2.6.6, and you have been using
openswan-2.1.2 in both the working and non-working situations, right? So, it'd
be safe to say that this is likely a kernel issue rather then a pluto thing.
Does anyone on this list have NAT-T on 2.6 working, and would that someone be so
kind to post his kernel revision, so I can try to get a working state? And maybe
go from there with tracking down the change that breaks things. In fact, has
anyone actually gotten NAT-T to work with 2.6/openswan *at all*? And was that
with a 2.6 initiator/responder or was 2.4 somewhere in play still? Or racoon,
maybe? Details, I need details, so I can get this working, so I can test if my
changes to KLIPS make NAT-T work for 2.6/KLIPS too :)
