In order to see a real ip address inside of your network there are a number of approaches, but one is to DNAT that the external ip address to your internal address. You in effect need a tunnel.

It is a small town, the homes are all single story and construction varies from block to wood frame with cardboard walls. He would like to have 4 or 5 students have internet access in their homes. The cable connection would be at the church and all of the homes would be within 500 feet or so. Some 2 streets away with homes in between. Trees exist. I purchased a book, Jeff Duntemann's "Wifi Guide". It is good book but mostly talks about extending ranges for large ranch style homes and does not go into enough detail for the project I am working on. Money is limited so I can not afford to do a great deal of experimentation. However from reading the book some is required in almost every case. I am hoping that I can use a Linksys WRT54G wireless router, put a 18 or 20dbi Omni antenna on a poll at the church and have Cantennas or some type of directional antenna on the desktops at the kids homes, and maybe have to put those on the roof. However so far it appears that all of the homes have a window facing the church and if we get the antenna up high enough they may have line of sight with the church antenna without having to loose signal to coax at the house level. We will already loose some to coax at the church. I feel that putting the router up on the pole with the antenna and using power over ethernet would not be acceptable in the hot climate of the central Arizona deserts. We have months of 110 degree F temperatures here. Can anyone tell me if this is a sound approach or know of a book which deals with requirements for projects such as I am attempting? Thank you so much for any assistance anyone can be.

If you have reasonable line of sight you should be ok. You might be better off with a sector vs omni at the church, they tend to be more cost effective. The wrtg should work, you can find some ap's with 200 and in some cases 400miliwatt radios, this would give you some more advantage if you need to blast through some trees. We have a few of the sites with fairly long 30+ feet coax but, lately have been putting the radio box in a weather proof box and just using a pigtail to the antenna and poe to the box. If you do use coax we found anything less than LMR400 give a lot of loss. Good termination and uv and water resistant sealing of ends of cable. max > -----Original Message----- > From: nocatnet-bounces at nocat.net > [mailto:nocatnet-bounces at nocat.net] On Behalf Of John Pearce > Sent: Tuesday, April 10, 2007 3:51 PM > To: nocatnet at nocat.net > Subject: [NoCatNet] Help with Distance > > Hello Everyone, > > I am trying to help a Priest in a small Yaqui Indian > community create a wireless network he wishes to use for a > school he is starting.

They're trivial to setup and automagically mesh together to find the best route up to about 4 hops. About $60 ea with tax/shipping. You can also buy them from www.netequality.net - Mike there is very helpful with working out with you where best to place them. Fwiw, I'd be tempted to try one on a pole with PoE. Much much less signal loss - and the price of a new radio if it does die is less than the cost of coax is likely to be. Propagation should be pretty good given the construction and likely existing low RF noise.
