Need to allow all ports on firewall, so one port can be redirected

Postby jisamaniac » 2018/01/08 19:37:16

Inside our DMZ, the policy is all internal OS firewalls are to be turned off. On our Graylog server 1024 and below are privileged accounts and Graylog doesn't have really documentation to run at the root level. My goal is to re-enable the firewalld to allow all incoming ports and redirect port 514 to something like 10514 for our Cisco switches to forward their syslogs.

Is this recommended or is there a better way of doing what I am wanting? Since Firewalld uses zones. What is the best method of enabling all ports allowed on the firewall and to redirect a single point?
