im sorry, im not an expert on this but heres what i have experienced in the past when i was in the UAE... i never tried it here because i gave up applying for personal ADSL because of QTELs wonderful customer service.

In the UAE port 8000 is open but i dont know what it is here. Anyway, the best site i found was https://antiproxy.com , the unsecure server will be blocked so you have to remember the https. excellent list of servers searchable by port number plus loads of other info.

good luck
