when I try to play this flash online game "" using our university proxy I get this error "Cannot establish connection (host:, ports: 4444,5190,5223,5222,5050)".

In windows I use "Microsoft Firewall Client for ISA Server" to solve this problem.

how can I solve it in ubuntu?

the problem is not from the browser because I have tried different ones and nothing worked.

You can't. Your university blocks these ports for a reason. – aquaherd Feb 27 '13 at 21:05

Most proxies restrict available ports.. talk to your network admin

OK, how come I can solve this problem using "Microsoft Firewall Client for ISA Server"? – Abdullah Ibraheem Feb 27 '13 at 21:10
By tunneling? Dunno, never used it. – Grizly Feb 27 '13 at 21:55
