CentOS - Forwarding all ports except one

  • 772

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

  1. 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.
