Problem is solved, but it was a forwarding problem, not a firewall.
I was just using my own local network to play, but when i used my outside IP adress it worked.
So thanks all for your time ^^

When i enter the AH it says "Search Failed.".
I check all firewall settings, they seam to be OK.
I realy enjoy the FFXI ^^
I played it for 4 years and still miss it.
Thank you for helping me, i hope to find a solution to this problem.
