There seems to be a problem somewhere. If I reboot the system and use my original kernel, then start shorewall everything seems fine. However, if I attempt to start shorewall using the OpenVZ kernel it doesn't complete and thus locks me out remotely.. I need to reboot, or shutdown shorewall with 'shorewall clear' in order to connect remotely again..

I know the problem isn't the shorewall settings since it works perfectly under the original kernel.. Initially I though it might be the iptable kernel modules, however I did a comparsion of both the modules loaded using the original kernel vs the OpenVZ kernel..

Both have the following modules enabled.

ipt_length
ipt_ttl
ipt_tcpmss
ipt_TCPMSS
iptable_mangle
iptable_filter
ipt_multiport
ipt_limit
ipt_tos
ipt_REJECT
ip_tables

I know that I can enable addition modules in /etc/sysconfig/iptables-config as per the documentation under advanced tasks ie: iptable_nat etc.. tried that and still nothing.

I'm not doing anything on the Hardware node that's complex, just providing a simple firewall using shorewall.. Any ideas??? anything else I should be checking???
