Are you like me who is behind a firewall but wants play FlyFF?

Here are the IP/Ports you need to set on your firewall settings:

FlyFF PH Login server:

Host : 202.57.108.151

Port : 23000

FlyFF PH Game server:

Host : 202.57.108.167

Port : 28000

Host : 202.57.108.177

Host : 5400

The initial page that displays announcements and gameguard connection

uses normal http connection and shouldnt be a problem at all.
