I am stuck with this problem: I installed HN with Debian stable (yes, it's Lenny at last). It was a minimal default installation with Debian openvz kernel (linux-image-2.6.26-1-openvz-amd64_2.6.26-13_amd64.deb). The HN runs smoothly and I have created a container with Debian Lenny minimal installation in it and it runs without problems as well. The story begins when I try to run NAT inside the container. Adding:
IPTABLES="iptable_nat"

in the container's conf file and trying to start it gives an oops:

------------------------------
kama:~# vzctl start 202
Starting VE ...
VE is mounted
Adding IP address(es): 192.168.1.202

------------------------------

Luckily it justs hangs the process of bringing up the container, not the HN itself.


Any ideas how to get around this problem? I need this NAT inside the container badly and I would prefer to stick with Debian kernel, maybe there's a kernel patch available so I could recompile the Debian kernel myself?

Thanks for any hints and help.
