I read it. This is what I got out of it. It sounds like I need to let the modem use DHCP with the phone company.

Dale, 

point 1 is that the problem you seem to have is that your two dhcp
systems are each giving out IP's from the same range, and as both are
starting at the same number, thats where the clash occurs.  Simple fix
is to change the ranges so they dont overlap.  Bottom line, you should
have only one dhcp server per network (as defined by the subnet mask)
unless you pin IP numbers (as in bootp),  use different ranges for each
or other trickery.  Or statically assign ip numbers and be done with it!

Point 2 is dhcp is non-routable as it broadcasts (as always, there are
ways to deal with this - but I dont think you have dhcp-relay going on.)
- dhcp clients broadcast for an address, and the server sends the
address back unicast - so clients on different network segments cant see
others broadcasts - for instance a layer 3 router blocks broadcasts.

point 3 is that the adsl modem is normally a dhcp client to the external
network (as its ip address is supplied by the ISP), and a server for the
internal network to supply IP numbers from its own pool of addresses to
your internal machines.

Point 4 is that the network design sucks.  Can you list what ip
number/subnet mask you have on the internal PC, the router internal
interface, the router external interface and the adsl modem internal
interface.  And on which device the NAT/firewall is happening (please
done say both ... :(

Point 5 ... thats enuf for now :)

Well, I'm not real sure at times what thing has what IP.  I found this on the modem tho:

IP Address / Name  MAC Address Connection Status  Connection Type
192.168.1.1/ fireball  1c-6f-65-4c-91-c7  Offline Ethernet
192.168.1.2/ 00259C49FD9D  00-25-9c-49-fd-9d  Active Ethernet
192.168.1.4/ *  1c-6f-65-4c-91-c7  Offline Ethernet
192.168.1.6/ *  00-25-9c-49-fd-9d  Offline Ethernet

The one that says "active" is the router currently connected.  I got it to working again.  ;-)  It looks like the modem "remembers" what is hooked up and what IPs it was assigned.  Neat huh.   I can't find the same thing in the router tho. 

I found a how to.  I read it.  This is what I got out of it.  It sounds like I need to let the modem use DHCP with the phone company.  Then I need to set the ethernet that comes toward the router to say 192.168.1.2 then set the router to 192.168.1.5 or something to come to my puter..  Then when I hook up my second puter, I can assign it 192.168.1.6 or something.  Best I can figure, no two can have the same IP.  Each device has two IPs, one coming in, one going out.  That part sort of confuses me a bit.  I need a chalk board for this.
