[Xitami] Cannot access site from outside. XP?

[Rob Catlin]

Hello all,

First off, I'm very green to Xitami.

I just installed Windows XP Home Ed. to find that they no longer allow PWS
or IIS (Good thing, right?)  I installed Xitami, PHP, and MySQL and can
access my websites great from my PC.

When I try to access them externally, though, I always get the "this page
cannot be displayed" page.

What config am I missing to get this to work?

Thanks,
-=Rob=-
