iptables error on pptp

Question

root@pptp [~]# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
iptables: Unknown error 18446744073709551615

This is an openVZ box. Is there a way to bypass that?

This is the MASQUERADE that is giving problems I am assuming. new to iptables so is there a way to do this differently

Answer 1

You must reconfigure the host (hardware) node to load the necessary iptables module(s).

In this case it appears you you need ipt_MASQUERADE.
