Hello,

I've searched the archives and still not found a solution (though many are close).

Please forgive the (likely) easy to answer question:

My ve's cannot use iptables:

iptables v1.3.5: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.


lsmod shows:

# lsmod | grep -i "tables"
ip_tables 18760 1 iptable_filter
x_tables 19204 10 ip_tables,xt_tcpudp,xt_length,ipt_ttl,xt_tcpmss,ipt_TCPMSS,x t_multiport,xt_limit,ipt_tos,ipt_REJECT



and /etc/vz/vz.conf :


# grep -i tables /etc/vz/vz.conf
IPTABLES="ipt_REJECT ipt_tos ipt_limit ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl ipt_length"
IP6TABLES="ip6_tables ip6table_filter ip6table_mangle ip6t_REJECT"


What am I missing?

Thanks in advance.

Make sure iptables modules are loaded before openvz modules.

Thanks.

How do I determine the load order?

Thanks again.

First check it manually. Stop vz service (/etc/init.d/vz stop) and run iptables (/etc/init.d/iptables start). Check that iptables modules (such as ipt_filter) are loaded. Start vz service. Try using iptables from inside VE.

Thanks Kir, I followed the instructions and it seems to have worked, however, I didn't change anything and now I'm confused as to what I've done differently, except stopping the entire VZ service, I was just stopping the VE's earlier with vzctl stop 101. Anyway, here is the output, I can see iptable_filter but not ipt_filter, maybe the same mod?

First check it manually. Stop vz service (/etc/init.d/vz stop) and run iptables (/etc/init.d/iptables start). Check that iptables modules (such as ipt_filter) are loaded. Start vz service. Try using iptables from inside VE.
