I know this a little bit off topic but maybe someone of you has experience
with this topic.

I want to run a hylafax install in an openvz container with iptables.
My Problem is that I can load the kernel module for ftp connection tracking
(nf_conntrack_ftp) in the containers config file but no idea how to set the
parameter to track the right ports.

My vz config looks like:

IPTABLES=”ipt_REJECT ipt_tos ipt_TOS ipt_LOG ip_conntrack ipt_limit
ipt_multiport iptable_filter iptable_mangle ipt_TCPMSS ipt_tcpmss ipt_ttl
ipt_length ipt_state iptable_nat ip_nat_ftp ip_conntrack_ftp ipt_conntrack
ip_tables ”

On the host machine the module nf_conntrack_ftp ports is loaded with the
parameter ports=21,4559.

With best regards
