[Devel] using iptables geoip in openvz container

[U.Mutlu]

Hello,
is the xtables-addons for iptables ( http://xtables-addons.sourceforge.net/ ),
for example the module geoip to block on a country basis, and the target TARPIT,
not possible in an openvz container?

I think it should work since iptables works fine, but a provider told me
that the above said modules/targets won't work in an openvz container.
Is that really true, or has maybe the provider not managed to get it working?

Thx
