Yes, OpenVZ needs to use the FORWARD table for iptables so that traffic from/to the VEs are routed through the HN.

I think the person in the Lxlabs forum did a great job to minimize any potential security risk associated with the use of the FORWARD table. However, you must use iptables to firewall your VE's afterward, either using FORWARD rules on the HN, or using iptables inside the VEs.
