If its the one connecting your two lans together how is it ever going to work? How far apart are these two lans can they be turned into one big one? Also what are these switches - routers or an ethernet bridge or a linux box? Can they be configured? How are the machines in the lans allocated their ip addresses - are you using dhcp and if so where is the server that does this? I assume this is all private addresses on a private network. In which case you should be using these ranges. 10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix) 192.255.255.* should not be used > > This choice came out of the blue and I do not > have time to work out my basics right ! > > I am too tensed up to think.

Well if your all tensed up then you are bound to make a mistake configuring this lot :-) > > One is Class A , the other is Class C , > so may be I will make all of them onto > Class A. I think these distinctions are not important these days. Just think of how many bits you want to use for address and set the netmasks appropriately. > > Well , my boss wants the Proxy (to the Internet) > {and later the firewall which I will then ask you} > to be on 192.255.255.1 .

How can you do this when your boss has removed the cable? - but seriously you will have to tell them the route - if its debian/linux that is acting as the switch/router then you can just do that by defining parameters in the /etc/network/interfaces file on each machine or with the route command (look at the man page for route) > > Is my line of thinking right ? ie: Converting the Class C > -based LAN2 's IP Addresses over to the 10.*.*.* , > so that both Windoze and Linux can see LAN2 . Where did these boxes come from. Give us some more clear facts about your configuration, types of connection between the lans and what you can configure and we may be able to help. At the moment you haven't given us enough info. Just out of curiousity - why did the boss pull the cable and why didn't he give you any advice as to how to solve the problem he had created by removing the cable? - -- Alan - [EMAIL PROTECTED] http://www.chandlerfamily.org.uk -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8Oeq/1mf3M5ZDr2kRAlVpAJ9AvTRhv7Pty0zZx57J7Rvc2FWU8wCgxEhY ULZBE4ImL+/wErGORNg22cI= =TBqJ -----END PGP SIGNATURE-----
