I'm not quite sure how to set up the LAN in my home. I have 4 computers, 3 of which are working just fine, including 1 with a wireless NIC. The fourth computer is a RH9 computer with a Netgear wireless NIC.

I need to configure the RH9 computer with the Netgear wireless NIC as an Apache web server so I can do some development. I'd like to prevent anyone outside of my LAN from accessing the RH9 web server. Additionally, I'd like the RH9 computer to have a static IP (this would make testing the web pages easier). I don't mind having the other 3 computers continue to use DHCP from the router, they work just fine that way.

One other important thing. I use 128 bit encryption for the wireless connections to the router, and I'd prefer to continue using encryption. This means that the RH9/Apache web server machine will need to be able to use encryption as well.

Can I make the RH9/Apache web server use a static IP address?
What host name/domain name would I use on the RH9/Apache web server?
Can I use the same encryption key the router already has?

Any answers and/or advice would be greatly appreciated.

Thanks.
