Hi, All

For many days I have been trying to get my OpenVZ VM to work with Netfilter Queue.

The VM IPtables version is 1.4.3 and the kernel is : 2.6.18

OS is Centos 5.5

The VM provider has said that nfnetlink_queue and nfnetlink IPTables modules are loaded on the VM. But when I attempt to run the command:

iptables -A FORWARD -j NFQUEUE

I get IPtables errors as follows:

iptables: Unknown error 4294967295

Please how can I fix this error and make OpenVZ VPS use NFQUEUE?


Thanks

Hi,

Can you check if nfqueue iptables extension is installed?

( # cat /proc/net/ip_tables_target )

you can find one at www.netfilter.org/projects/libnetfilter_queue/downloads.html

if installing extension does not help,
there's a bug report at bugzilla.openvz.org/show_bug.cgi?id=1677
and this thread forum.openvz.org/index.php?t=msg&goto=44169&

you may also want to reference 'man vz.conf' for the manual page of /etc/vz/conf/vz.conf or /etc/vz/vz.conf which has an IPTABLES* variables controlling iptables modules available for containers
