You must have changed something since the previous log snippet that you
posted, because UDP port 4500 is only used when NAT is involved.
What does "NAT-Traversal: Result using draft-ietf-ipsec-nat-t-ike-02/03:"
say? Did you move the server behind a NAT router? If so, did you remember
to use leftnexthop and did you apply the registry patch to your Windows
box if you use XP SP2 or higher?
