I am trying to setup a simple port forwarding on an OpenVZ container that is running CentOS 5.5. When I run a command I get errors.
iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080 iptables v1.3.5: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded.
The same command works fine on hardware node or any other physical server. I know that I can setup port forwarding for that particular container on hardware node, but thats not a solution.
