How to open a port?

[YaBoi]

Hello,
Hope al is well. I came onto this site in the hopes that someone oculd give me some instructions on how to open a server port. I have root access, but am really unsure of any of the necessary steps to take in order to open a port.

Any help would be greatly appreciated.

That depends on how you have it firewalled...

If you're using APF, edit the /etc/apf/conf.apf file. Look for "ingress" which are ports opened to allow traffic from the outside in. There are a couple of sections based on whether it's tcp or udp traffic, icmp, etc.

Once you've made the change, you'll have to restart APF : service apf restart

If you're using another method... post what you're doing.
