yes, that is right. I also have plenty of time to do this, so I may as well take it step by step til I get it. >> Besides buying a wireless bridge, is there some way for the connected >> machine to provide internet connectivity for this other machine? > > Yes. Very easily as a matter of fact. Install a wired network card I believe I have one. The output of lspci shows a Realtek card. Is this what you mean?

Ok, either I have one per the lspci output below or just need to know which one I can get for my Toshiba P25 high-end laptop: http://www.pcmag.com/article2/0,1759,1616847,00.asp This is the machine with a wireless connection. I have an itty-bitty Thinkpad 560e that needs to get connected to the internet via the Toshiba. > * Configure the second wired network card with a static IP address. > Use a different subnet than you have on our WAN side.

I might be there by this Saturday. But no biggie on time. Education is the key. Maybe I will type up a doc on this. In fact I certainly will if this works out... I have seen someone else do this with Debian 5-6 years ago, so I know it will work. > > > * Ensure that packet forwarding is in place.
