We found 2.6.6 and 2.6.7 were problematic from an IPSec perspective...

We are currently using 2.6.8.1 but need three patches. One to add
TTL & IPSec policy support and the other two to fix bugs:
http://www.webcon.ca/~rhardy/ivtv/linux-2.6.8.1-20040823-TTL+policy.patch.gz
http://www.webcon.ca/~rhardy/ivtv/linux-2.6.8.1-fix_htb_oops.patch.gz
http://www.webcon.ca/~rhardy/ivtv/linux-2.6.8.1-ck6-bugfixes.patch.gz

YMMV. We currently use 2.6.8.1 w/ Openswan 2.2.0dr4 (or later) tools.
We are using gcc-3.4.1.

Regards,
Rob
