I got an issue with iptables on my virtual machines.
I installed proxmox 3.1-21 on my rootserver. I have around 6 IPs linked to my rootserver so i created new 'CT's.
The problem is i need to redirect ports to a destination port, the command for this is this:
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 10001 -j REDIRECT --to-port 9001
The problem is, my ct does return me now this error:
iptables v1.4.21: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded
How can I fix this issue? I already looked around on several websites. I also found the directly same question somewhere on a proxmox forum where no one replied.
