Very Computer

I am almost there, just a few more questions !!! :-)

We are using our linux box as an internet gateway/firewall with ipchains and
masquerading.

It is, also, use as DHCP server.

Is it possible to limit the internet access to specific computers.  Since
the ip address could change on each reboot, how can we block access ?

Thank you

have not done this so just a few thoughts....

might be possible to block by name not by adress,
or give certain hosts a ipadress from a different range,
or not give them routing info.

but....

i imply you use  a small network, with private numbers
(like 192.168.x.x).
whats the point in using dhcp at all?
i tried it, it works -
so i know it can be done.

but you dont have a limit of adresses, and need your hosts to give them
back after a while, right?
so use fixed adresses, might make things easier.

Before you buy.

I saw on ZDTV that Squid could be used for this, but giving that you are
using DHCP you may have to specify ranges of addresses to limit.
