Hi folks,
My setup:
Computer 1: PPC G5 running Leopard with an Epson Stylus CX4450 printer.
Computer 2: B&W G4 running Tiger
Airport Extreme Base Station: Brother Laser printer connected to it via USB
Network: I was "updated" by my ISP with their latest DSL modem recently.
Now their version of a DSL modem is not just a modem but also a 4 port
wireless router (I disabled the wireless feature). I also have an Airport
Extreme base station because the previous modem I had only had 1 port.
As an aside to your current problem, I believe you can configure the
Airport Extreme Base Station (AEBS) to act as a network connection.
That is you use the wireless Access Point feature of the DSL modem. You
then set up the AEBS to connect wirelessly to the DSL modem. The AEBS
serves the attached USB printer and any computers connected via wired
connection. In other words you could make the printer wireless. I'm
not certain this feature is supported in the AEBS but I believe it is.
I wanted to keep using the Airport base station because I can connect our
laser printer to it via USB. So I connected the Airport station to the new
DSL modem/router. Everything works just fine. I have 2 other computers
(aside from the G5) connected to the Airport and all 3 can print to the
laser printer.
My problem: Since the Airport only has 3 ports and all are being used, the
B&W was left out of the party. I decided to connect the B&W to the DSL
modem/router (it had 3 other ports available). The B&W has full internet
access BUT it can not print to the laser printer. I also wanted to print to
the G5 which is sharing it's Epson Stylus printer. The other 2 computers
connected to Airport can print to the Epson BUT again the B&W can not.
So, to sum it all up:
Airport Base Station connected to DSL modem/router.
G5 along with 2 other computers connected to Airport Base Station.
B&W connected to DSL modem/router.
Laser printer connected to Airport via USB.
Epson Stylus connected to G5 and is set to "share".
None of the computers are wireless.
Is there a way for the B&W to printer to the Airport Base Station and/or
print to the G5?
The problem, I think, is that both the DSL Modem and the AEBS are
providing Network Address Translation (NAT). Also known as double NAT.
NAT is what allows a router (such as is part of the AEBS and DSL
modem) to make a whole network of computers on the LAN side appear as a
single IP address on the WAN side.
The DSL modem's WAN side is connected to the Internet. The DSL modem's
LAN side is connected to the B&W and the AEBS's WAN side. The AEBS's
LAN side is connected to all the other computers and the AEBS's print
server. What you have then are the Internet and two discrete LANs which
have limited access to each other.
The B&W is isolated on a network that can only see the Internet via the
DSL modem.
What you are trying to do is create a single LAN. To do this you need
to get a 5 or 8 port 10/100 switch. They are pretty cheap and can be
purchased at most places that sell computers and related equipment.
You connect the switch to the DSL modem, each computer and the LAN side
of the AEBS. You will also need to configure the AEBS to not do NAT,
DHCP or wireless.
Alternatively you could leave the DSL modem connected to the AEBS and
put the switch between the AEBS LAN port and the computers. This avoids
having to reconfigure the AEBS but it does mean you will be doing double
NAT still. It will cause a slight speed penalty on Internet access and
can be a configuration problem waiting to happen, especially if you
don't understand it.
