I want to redirect all ports from VPN server to one of VPN client (except the SSH-5656 port and OpenVPN port-5757).

I know this command:

iptables -A FORWARD --proto tcp -p 1-5655 -j DSTNAT -d 10.8.0.x

But I don´t know, how to redirect more ports with one command.

For example: I want to redirect ports from 1-5655 to client 10.8.0.2 (TCP + UDP) and then I want to redirect 5657-5756 & 5758-65535 (both protocols) to the same OpenVPN client.

Can you please help me with that?

Thanks :)

There is the parameter multiport

-m multiport --dports 1:5655,5758:65535 -j DSTNAT

Edit: with "-m multiport" specifies a match to use. In our case the module "multiport", after that is necessary to specify the destination (--dport) or source (--sport) port range with the syntax "from_port:to_port". You can add additional port range by separating it with a comma, for ex. (1:5655,5758:65535).

Note: "multiport" can only be used by specifying the protocol with -p tcp or -p udp
