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

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

In this case it appears you you need ipt_MASQUERADE.

Can that be done in OpenVZ? what host said: Since MASQUERADE is not possible to virtualized , You can configure many to one NAT to an IP alias, using the POSTROUTING instead of MASQUERADE statement –  Mike Janson Jan 4 '13 at 6:14
    
Oh, this isn't your server, then? Use a VPS provider that doesn't use OpenVZ then. –  Michael Hampton Jan 4 '13 at 6:29
    
Does ipt_MASQUERADE work with OpenVZ? Or am I stuck having to find a XEN. I could ask them again I might have missed sending ipt_MASQUERADE –  Mike Janson Jan 4 '13 at 6:39
