Open Up Port On Filewall(s)
This is how to open up a port on the APF and iptables firewalls.
If you change the SSH port you MUST open up the port or you will get locked out of the server.
1- Go to:
edit the confil file:
2- find this line:
Add the port(s) you want to open to the list there already.
3- Restart APF
1- If you want to open up port 25 ... issue this command:
iptables -I INPUT -p tcp --dport 25 -j ACCEPT
2- Change that port number for what number you need to open
3- Repeat the command for each port to open
