However, things are more complicated than you assume and I now wonder if I will be able to accomplish all I want to do. Briefly, I'm in my 70's and have medical problems, so originally I had one box in the bedroom (complete with modem, printer, CDRW and so forth) and another in the lounge also with modem, printer etc. giving me 'full facilities' wherever I was. Following upgrades I built a third box intending to use this for a firewall (I even have a modem for that). I obtained a hub, cabling, NIC cards etc intending to have a 'cosy' little network. A neighbour, living in the flat above saw the bits and pieces and said he had ADSL which I was welcome to use (ideal for heavy downloads eg kernels) so I cabled to his network (box and laptop). Initially he ran Windows, so I installed W98 and we exchange photo editing, music data etc and also have a networked printer. I use the ADSL when beneficial. He has now been converted to include Linux, he won't go yet to Debian, but Mandrake will do for a start. So far I've put Woody on only two boxes (bedroom and lounge), and I wanted each to have modem access to my ISP and in due course to be able to access the ADSL. This way I don't always have to bring the network up if I'm likely to be restricted to one room. In this case, I assume I'll need more than one gateway. Paul Condon suggested using 192.168.1.x - this is what I have planned (I've laid out my scheme to use .4, .5 and .6 for the three boxes - I'd like to suggest I was being clever, but it was just so that I could leave 192.168.0.x for my neighbour). Routing for both boxes excludes the ppp0 entry, so this must be the problem taking each box in isolation. I shall try to get one working tomorrow. Then I shall have to see how to proceed from there. If you have any advice overall on what I said above, I shall be very grateful. What you have communicated so far has been a very great help in understanding. Very many thanks and regards, john. > I'm probably going to cover some ground that you already have, but > maybe you'll get something new out of it. > > Box 1 has the modem, Box 2 and 3 don't.
