[Openswan Users] NAT-T patch don't work

[Filippo Conti]

Hi all,
I'm tryng to compile a vanilla linux kernel whith KLIPS and NAT-T, when 
I apply NAT-T patch i get:

"3 out of 6 hunks FAILED -- saving rejects to file net/ipv4/udp.c.rej"

I've tried 2.6.18.8, 2.6.22, 2.6.22.1, 2.6.22.11, 2.6.22.16, 2.6.23.1, 
2.6.23.14 with OpenSWAN 2.4.11 (some test with 10 too) and the error is 
the same.

KERNELSRC=/usr/src/linux (a link to the kernel's folder)
cd /usr/src/openswan-2.4.11
make nattpatch > /usr/src/openswan-2.4.11-ipsec-natt.patch
cd $KERNELSRC
cat /usr/src/openswan-2.4.11-ipsec-natt.patch | patch -p1 -s

I'm running Cent OS 5 in i386 (all patch applied),
Regards.
