how to use jtag server

Sorry to hooking on to this question, but I have similar problem on using the jtagserver on windows xp sp2.

Search on www.altera.com and nios forum on jtagServer gives surprisingly little help as to how to actually use the jtag server.

1.) Whats the syntax to use on the client side to identify the server?

2.) How to setup the windows firewall to enable the necessary ports? I guess I need to know the ports used by the server in order to open these?

In my case I use usbBlaster but

any hints and manual pointers are appreciated
