[lug] Networking Question

[Joseph McDonald]

Hi gang,

I have a question regarding my new home network setup and here's
a pretty lengthy explanation:

Configuring an MSN Broadband (a-la Qwest) to work with a 4 port
Linksys BEFSR41 and a D-link DI-614+ wireless router. Qwest told
me that they would only support a single PC connected to their
DSL router and I'd be responsible for configuring the network
should I decide to add a DSL router. 

I have the following equipment connected and working: 

1. Microsoft Broadband DSL 1000 Router
2. Linksys BEFSR41 4 port DSL router
3. Dell PC 
4. Dell PC 
5. Sun Ultra Sparc II (Solaris 8)
6. D-link DI-614+ wireless router.
7. Dell Insperon 5000 Laptop

They network starts with the Microsoft 1000 DSL router. The
external connection is DHCP assigned and the internal (gateway)
address is always 192.168.1.1. The subnet mask is 255.255.255.252
which means I only get one IP to use (so you can't plug in a hub
and expect to be able to get more than one IP). I configured my
Linksys to do DHCP off the MSN 1000, then the LAN was configured
to use 10.0.0.0/24 (Linksys internal static address of 10.0.0.1).

This worked, but for the next 3 or 4 days, every 20 or 30 minutes, 
I'd drop packets for about 30 - 60 seconds. So, I decided to assign 
the Linksys an external static IP of 192.168.1.2, which cleared up 
that problem. I guess it was trying to get a new DHCP lease from 
the MSN 1000 every 20 or 30 min.

I connected 3 PC's to the Linksys and gave them all static
addresses in 10.0.0.x with a gateway of 10.0.0.1 and subnet mask
of 255.255.255.0. All worked fine.. Then I ran some cat5 upstairs
and plugged in the D-Link. I assigned the D-Link an external IP
of 10.0.0.3 and have it's internal IP as 192.168.0.1. It's handing
out DHCP addresses in that range (/24).

Now, all PC's can get to the internet although systems on the
10.0.0.0 network can't ping systems on the 192.168.0.0 network.
I've added a static route to the Linksys as follows: 

192.168.0.0		255.255.255.0	10.0.0.3	1	LAN 

but that doesn't seem to do the trick. Does anyone think they 
know what the problem could be? Here's my network layout:
