>From an exhaustive struggle to get NAT-T working with the 2.6.5 native
ipsec stack & openswan 2.1.x, I've found the following to be true.
NAT-T with Win XP client works when the client only is NAT'd. When the
freeswan box is NAT'd, the connection fails immediately after MR3,
ISAKMP SA established... With "cannot respond to IPsec SA request
because no connection is known". When both client and swan box are
NAT'd we get no further than transition from state STATE_MAIN_R1 to
Can anyone dispute these results or concord?
