Problem with isakmpd and Windows 2000

[Matt Hempel <matt%epana.com@localhost>]

I've been looking for alternatives to racoon for IKE on netbsd.  isakmpd 
was one option, but it (build isakmpd-20010403) bombs with anguish when 
trying to connect to Win2K via IPSEC:

bash-2.05# isakmpd -d
130734.432125 Default pf_key_v2_flow: SPDDELETE: Invalid argument
isakmpd in free(): warning: junk pointer, too high to make sense.
130735.373160 Default pf_key_v2_flow: SPDDELETE: Invalid argument
isakmpd in free(): warning: junk pointer, too high to make sense.
130737.373135 Default pf_key_v2_flow: SPDDELETE: Invalid argument

130749.382796 Default pf_key_v2_flow: SPDDELETE: Invalid argument
isakmpd in free(): warning: junk pointer, too high to make sense.

as these errors were presented, the box spewed packets to the Win2K box in 
rapid succession:

Anybody have success with isakmpd?  Is there a more stable version I should 
seek?  I found only scarce docs around.
