Overview
Change the Default Port
Uncomment and/or update the default "Port" value in /etc/ssh/sshd_config:
#Port 22 Port 12345
Change the Default Port on a SELinux System
If SELinux is enable, you have to tell SELinux about the port change:
semanage port -a -t ssh_port_t -p tcp 12345
Update the Firewall Rules
If iptables is enabled, there's a firewall rule that allows ssh access, and it usually mentions the port. You may want to check and change that: Iptables_Command_Line_Tool_Examples#Allow_SSH_Only_From_the_Internal_Network_on_a_Non-Standard_Port
