Firewall - UDP ports

[R3N3GADE]

Hi,

I need to open some UDP ports on the plesk firewall.
I understand I have to edit the "pfwmng.js" in admin/bin.

This is the default config:

var PortsUDP = new Array ("0", 53, 53, 0, 123, 123);

I wanted to open port 7777. So I changed it to:

var PortsUDP = new Array ("0", 53, 53, 0, 123, 123, 7777, 7777);

That didnt work, but this did:

var PortsUDP = new Array (123, 123, 7777, 7777);

Do I need to have the "0" & "53" in there?
