Tried that, same result - it fails with this:

ipsec: Unknown symbol ipsec_nat_encap

The ipsec_net_encap is a rutine applied to the kernel when patching it 
with the nat-t-patch, but get's a lot of faults:

[root at Boomer linux# patch -p1<../nat-t-patch-2.6.diff
patching file include/net/xfrmudp.h
patching file net/ipv4/Kconfig
Hunk #1 succeeded at 351 with fuzz 1.

Hunk #1 FAILED at 108.
Hunk #2 FAILED at 882.
Hunk #3 FAILED at 914.
Hunk #4 FAILED at 1044.
Hunk #5 FAILED at 1153.
Hunk #6 succeeded at 1690 (offset 49 lines).
5 out of 6 hunks FAILED -- saving rejects to file net/ipv4/udp.c.rej

Tried several kernels, from to - without luck, so i 
need to know which kernel the nat-t-patch was tested against.
