Mac OS X VPN Client with NAT-T support?

[Sean <sean_(_at_)_obstacle9_(_dot_)_com>]

Hey All,

As the subject states, I'm looking for a NAT-T capable IPSec client for
Mac OS X-- preferably something GUI based. Clients I've looked at but
don't cut it:

VPN Tracker: doesn't support NAT Traversal yet
OS 10.3.4 native IPSec: LT2P only and a non-standard NAT-T
implementation as far as I know, can anyone confirm?
VaporSec: doesn't support certificates
IPSecuritas: NAT-T support supposedly there, but doesn't seem to be
working. According to
http://www.jacco2.dds.nl/networking/freeswan-panther.html#NAT-Traversal
, Apple didn't implement standard NAT-T support into OS X, which
IPSecuritas depends on.
Cisco VPN Client: uses XAUTH only

I'm also trying to compile isakmpd on my Apple, although I'm getting
"math_mp.h:52:2 #error "No multiprecision math library chosen." errors
when I attempt to compile.
