Why isn't my linux firewall opening ports?

I’ve been fussing around with opening up 1 simple port on a dedicated linux server which is using “Linux Firewall” iptables.

I’ve added the port (3306) in the tables using Webmin and terminal but it still will not let me connect remotely.

I’ve restarted iptables many times and it still won’t work.

Here is the output of iptables -L
