I've recently set up an ubuntu server to host my site - I need to open up port 3306 for MySQL access on my server.

I'm currently using shorewall on my server - how can open incoming connections to 3306 in shorewall? - Here are my current rules (enabling incoming for 80/HTTP and 22/SSH).

```
ACCEPT        $FW        net        icmp
HTTP/ACCEPT   net        $FW
SSH/ACCEPT    net        $FW

```

What is the rule name for the MySQL port (3306). Also, is it possible to enable ports just by port not by a name?
