[Openswan Users] steps to load KLIPS IPSec stack in 2.6.13 kernel

In IMS-AKA (IP Multimedia Subsystem - Authentication and Key Agreement)
scenario, authentication and associations are taken care by SIP protocol.So,
no IKE happens. So to
very much simplify this scenario, as a first step, I want to "manually key"
with the main motivation to verify "UDP encapsulation". Then the next step
would be to use SIP to establish assocations. So manual keying would be the
first step for this. Already its possible with setkey to use manual keying,
but I am not able to force it to UDP encapsulate the packets. But, with
pluto using NETKEY IPSec stack, in automatic keying I am able to force NAT-T
and in effect UDP encapsulation. But, I do not want IKE to be run and just
want to force "UDP encapsulation" and the obvious choice is "manual keying".
When I try to force NAT-T using manual keying, I get the following error
ipsec manual: fatal error in "man": no IPSEC-enabled Interfaces found
As I googled and went through the archives for solving the above error, it
was suggested to use KLIPS stack instead of NETKEY stack and this is the
reason I wanted to move to KLIPS stack.
So, I would like to know if NAT-T can be "forced" in manual keying with
KLIPS IPSec stack and is it a good idea to do that, or this can be just done
with the NETKEY IPSec stack itself and there is some possibility to solve
the above error.
Thanking you very much,
