  • Thanks but is it possible to forward all ports without making that commands for every port?

    With what, iptables?
    Also I doubt you want to forward all ports, if you do you might get locked out of crucial services such as SSH. Something along this line should work

    iptables -t nat -A PREROUTING -p tcp --dport 1024:65535 -j DNAT --to-destination 10.9.0.18:1024-65535 Make sure to change the destination IP.

  • Okay thanks!

  • I'm getting this error with that command

    iptables v1.4.14: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)
    Perhaps iptables or your kernel needs to be upgraded.

    Open ticket and ask your provider to enable nat , or if it's your openvz node:


    nano /etc/modprobe.d/openvz.conf

    and change


    options nf_conntrack ip_conntrack_disable_ve0=1

    to

    options nf_conntrack ip_conntrack_disable_ve0=0
