Hey All,
When installing the ipsec-tools it says if you want NAT-T you need to install this patch, http://ipsec-tools.sourceforge.net/freebsd6-natt.diff Can any one tell me if this patch works with Fast_ipsec or is it just for the other ipsec?

Hi.

I didn't have time to port it to FAST_IPSEC now, so it currently only
works with IPSEC.

But FAST_IPSEC support is on my TODO list, and shouldn't be too
difficult.... when I'll have time to work on it, and when we'll
synchronize with other people who are actually working on IPSec
stacks.


Yvan.
OK cool, the thing that really turns my off about that IPSec is when I reboot with it compiled in says "Expect reduced performance" because its not mpsafe.

Also I just tried to compile a kernel with that Nat-T patch on the other IPSEC kernel on 6.1-release and it failed. I can't think of anything I have done wrong on this machine its pretty fresh, I did cvsup with "RELENG_6_1" before hand maybe there is a tiny enough about of changes since the RELENG_6_1_0 release for it to fail but I didn't notice anything serious changed, I also used the new pure C csup over cvsup client.

The patch installed fine with no errors but the kernel failed to compile ending with this..

/usr/src/sys/netinet/udp_usrreq.c:1046: warning: 'udp4_espinudp' defined but not used

The kernel was quite generic listed here below, the GENERIC2 just missing a few things like scsi and raid bits this machine doesn't need.
