O.K. I am putting a fictitious situation as follows : Linux server with iptables firewall acts as Gateway for internet configured as DHCP server with only mac address setup in DHCP configuration file, having win 98 clients. Another Linux server acts as File server, having it's owm iptables rules to block unwanted mac-addresses same win 98 clients also acts as DHCP server. Now win client setup have Gateway IP as IP of Internet Gateway and WIN server IP as IP of file server. DHCP HOWTO asks to add following lines for individual clients in DHCP configuration file. #### host xyz { hardware ethernet 08:00:2b:4c:59:23; fixed-address 192.168.1.222; } #### In this case Can i use above setting by eliminating line specifying IP address (fixed-address 192.168.1.222; )? so that IP addrress/subnet of client will not be known to anybody. Now if outside user with Laptop try to connect to this network with one of the network switch, with concent of any win 98 client user and in absence of administator by assigning any IP address of any subnet (By trying permutation combination of 192.0.0.0, 10.0.0.0, 172.0.0.0) then will not get access to any win 98 machine by netbour neighbour. I am not sure whether this will work, I should try but in the mean time is it feasible? Hope i have made requirements clear. Thanks for support. --- Sanjay Arora <skpobox@xxxxxxxxxx> wrote: > On Tue, 2004-08-24 at 23:00, Jason Opperisano wrote: > > > > > so, essentially, put every machine on its own > dedicated subnet and have all traffic routed through > the firewall? that sounds scalable... > > > > -j > > > Never claimed scalable ;-) > > Sanjay. > > > > --- Sanjay Arora <skpobox@xxxxxxxxxx> wrote: > On Tue, 2004-08-24 at 23:00, Jason Opperisano wrote: > > > > > so, essentially, put every machine on its own > dedicated subnet and have all traffic routed through > the firewall? that sounds scalable... > > > > -j > > > Never claimed scalable ;-) > > Sanjay. > > > > __________________________________________________ Do You Yahoo!?
