I don't know it is a direct block or not, I see many around playing WoW at this location but no FFXI.

All links work fine, even POL website, however it is only when I open up POL is when it gets cut off, none of the connection sound or anything.

Shows IP Address and Default route, that's it.

Don't know what else I can try, would help alot if I knew what is the address the app uses to establish a connection I can then check if their firewall is specifically blocking that.
