[K12OSN] Router mystery

[Eric Brown]

There are a lot of unknowns here.  I'm going to guess that your cable modem
is pushing out DHCP.  I also bet your WAN link on your router is set to take
DHCP, and I bet it's also pushing out DHCP to your internal network.

I know on my K12LTPS setup, eth1 is the card used to send linux out to the
clients, so it has a static IP of 192.168.0.1, and it pushes out DHCP.  Have
you tried plugging eth0 into your router? 

If you intend to try out a thin client in your home, I don't think it will
work with your router.  You'll need a switch (or a hub will do if you're
just going to test one thin client).

I'm really just guessing in the dark here, but if your setup is like most
who aren't familiar with networking, I think I'm close.

I'm a newbie  trying to test k12LTSP on my home network that consists of:

cable modem --->Netgear MR814 Router--->PCs

When I connect the k12LTSP server  (eth1) to the router it doesn't see
the Internet.

When I connect  the k12LTSP server  (eth1) directly to the cable modem
it DOES see the internet.  Why?

Is there any way I can put the k12LTSP server behind my router so my
Windows stand-alone machines can share internet access?

I also use VOIP (Vonage) , so when I am using k12LTSP on the internet,
I lose phone service. Obviously this is not winning me any friends in
my household.

How can I connect eth1 to my router, so the Linux workstations have
access to the internet?

I also have a linux box loaded with FC3 and just a single NIC,
connected to the router and it HAS internet access.

What do I need to do to get k12LTSP to see the internet behind my router?

Maybe one day Linux will be less of a mystery to me, but right now...
