How to enable network ports you want?

You can edit /etc/sysconfig/iptables (RHEL/CentOS) or /etc/default/iptables (Debian/Ubuntu), add the ports you want to open in it, such as:

#-A INPUT -p tcp -m multiport --dport 80,443,25,465,110,995,143,993,587,465,22 -j ACCEPT
-A INPUT -p tcp -m multiport --dport 80,443,25,465,110,995,143,993,587,465,22,10000 -j ACCEPT

And then restart iptables service to make it work for you:

# /etc/init.d/iptables restart
