[Xitami] Intranet questions

[Just]

Hi all,

Newby questions again:

My current setup is DSL>modem>Linksys>PC#1 (Xitami); with forwarding on
Linksys so all port 80 calls points to a PC#1's IP address.  I am using
Register.com as my external DNS server.

I want to set up an intranet for all PCs under the Lynksys.  I can get it to
work as localhost.

Question: Is there a way to name it to something other than localhost?
Question: If I want to install another Xitami in say PC#2 for this intranet,
and leave PC#1's Xitami for all external calls?  how should I do it so it
won't fight with PC#1's Xitami

Thanks for helping
