Opening firewall ports

I'm trying to play Magic:The Gathering Online. They say that I need to open the following ports: 9896 and 16000-16999. I know how to open the singular (9896) port but I am clueless on how to open ports 16000-16999 without adding service definitions for each 999 ports. There has to be an easier way.

What Firewall are we talking about here?

There isn't an easier way for the builtin Internet Connection Firewall (or
Windows Firewall in XPSP2). Although you could script it, you would still
have 1,000 separate entries.

Yeah, I forgot to mention but it is the built in firewall that XP has. Do you know of any firewall that would allow a range of ports to be opened easily? Perhaps a freeware or shareware one?
