I am not the best at clarification , let me try to clearly
explain. Although the dual dhcp thing might be the problem.
OK here it goes. The linux box has its internet conection by
PCI wireless card so the internet to the back room is only by
wireless. So that I dont have to buy multiple wireless cards
I figured to make use of what I have. I have the linux box up
24/7 and it has a built in nic so I figured to use that as a
"server" to the D-link router(which is also just laying
around. The D-Link is set as a dhcp server. I have multiple
macs and a few other tower units (windows and linux). If the
D-Link is hooked up I can then just plug and unplug as I need
the other units to be online.
Now if there is a problem with the linux box being a dhcp
server to the router which in turn is a dhcp server then I
guess the linux box would have to still be a server to the
router but using a static?
Networking is not even close to something I comprehend fully
and I get just more confused as I read more, mostly the
terminolgy is difficult to put in context. In plain and
simple terminolgy here is what I would like to do
!. get the linux box to act as a server to provide internet to
the router/firewall
2. Have the router/firewall act as a server so that I may plug
in different units that I am testing or working on.
3.I would like to use the existing hardware that I have. i
have plenty of nic's and a ton of cable, two different
router/firewalls/.
The problem with wireless with the mac is the macs use 40 bit
wep and wont hook up to the 64 bit wep on the wireless so in
order to get internet access for the macs I have to either
have a cable(rj45) connection or have to use mac
airport(expensive) which I do not want to buy.
With everything that can be done with linux there has to be a
way to use the linux box with its wireless internet access to
provide internet access to the other units in the room, I
just dont have a clue on how.
For now I will try to have the D-Link issue static IPs and see
if I can connect, but I would prefer a dhcp because it would
be easier when I hook up other boxes.
Thanks for the input, I'm off to try.
