which version of openswan is that? I believe in 2.4.5 it was mistakenly
checking for nat-t while support for detecting nat-t was not in that
version of klips.

You can also see if nat-t is working by looking at the ipsec start logs.
You will see something like:

Feb  6 19:27:35 newpack ipsec__plutorun: Starting Pluto subsystem...
Feb  6 19:27:35 newpack pluto[4186]: Starting Pluto (Openswan Version 2.4.4 X.509-1.5.4 PLUTO_SENDS_VENDORID PLUTO_USES_KEYRR; Vendor ID OEz}FFFfgr_e)
Feb  6 19:27:35 newpack pluto[4186]: Setting NAT-Traversal port-4500 floating to on
Feb  6 19:27:35 newpack pluto[4186]:    port floating activation criteria nat_t=1/port_fload=1
Feb  6 19:27:35 newpack pluto[4186]:   including NAT-Traversal patch (Version 0.6c)

If you see [disabled] it means you didnt specify nat_traversal=yes
