CentOS - Forwarding all ports except one

Question

It is possible to forward all ports (TCP/UDP) in a CentOS server except by the ssh/sftp port (TCP port 22).

If it is possible how can I do this?

I thought in something using "FirewallD".

Thank you! =D

All for the same "ip" which in turn will redirect everything to other machines. Let's assume that the ip is `192.168.56.123`. Thanks! — Eduardo Lucio, Jul 02 '19 at 17:28

You will have to build a NAT solution, you may use IPtables for this purpose.

Here is a good article for you: RedHat iptables

You may also do something fancy and use LVS. This will essentially enable you to forward packets to multiple destination and work as a load-balancer.
