NS8 Firewall ports status Change, Open, Close, Internal, External

[dnutan (Marc)]

Untested. Probably through firewalld’s firewall-cmd with --remove-port option similarly to the ones here:

NS8 Change node SSH port 22 permanently

This is a shorter alternative procedure based on firewall-cmd only: firewall-cmd --permanent --add-forward-port=port=2222:proto=tcp:toport=22 firewall-cmd --permanent --service=ssh --add-port=2222/tcp firewall-cmd --permanent --service=ssh --remove-port=22/tcp firewall-cmd --reload Check the configuration with firewall-cmd --list-all I didn’t test it, but It should work on Debian, too.

From TL;DR man examples:

• View the available firewall zones: firewall-cmd --get-active-zones
• View the rules which are currently applied (always wise to know “default” rules before changes): firewall-cmd --list-all
• Permanently open two arbitrary ports in the specified zone:
  firewall-cmd --permanent --zone=public --add-port=25565/tcp --add-port=19132/udp
• Reload firewalld to force rule changes to take effect: firewall-cmd --reload
