I would take things in small steps. Get each step working beofre moving on the the next step.
Mikkel,
My ISP is Verizon Online. I will have to check to see if they are
blocking, but I don't think so as you will see below. The Westell
modem is also a router with one port. I tried having the modem
handling the PPoE and the router set to a static IP in the range of
the subnet specified by the modem.The router modem was set with port
forwarding to the router and the router was set with port forwarding
to the linux box (also a static ip on the subnet). At this point I
could ping the assigned dynamic IP (I use http://www.dnsstuff.com). The Linksys router showed nothing in its incoming logs. The Windows
boxes could access internet sites by IP only. The name lookup was no
longer working. The linux box was fine. This was when the Linksys
rep said that the modem had to be in bridge mode. Once put into
bridge mode, I could no longer ping the assigned IP, but the Windows
boxes could access the named sites. The router is now handling the
PPoE and DHCP.
My goal is to have the linux box control the other boxes. I think that you are right in that I need to set up DNS. There is a setup for that in drakwizard, but I do not know what to do with it. I believe that it asked me to change the hostname. I explore more when I get home.
Thanks for the help everyone.
If you are going to use the Linux box as a dhcp server, get that set up first. You will have to specify the address of the Linksys box as the gateway, and you also have to specify the name server as part of the dhcp setup. If I remember correctly, the Linksys box acts as a caching name server. If so, you can use that as the name server for the initial setup. If not, take a look at /etc/resolv.conf - you can use the name servers listed there at first.
option routers 192.168.0.1; option domain-name-servers 192.168.0.1;
If you are running Samba on the Linux box, and it provides a Wins server, you may want to add:
option netbios-name-servers <IP of Linux box>;
You may want to look into running dnsmasq on the Linux box, and having the Windows boxes use the Linux box as their name server.

I like it because it will read the /etc/hosts file on the Linux box, and add that to its database, as well as watching /var/lib/dhcp/dhcp.leases and adding hosts assigned IP addresses there. It works great for small networks. I have not tried it on a large network. It also works good with dialup connections.
Once you have this working, set up the services you want to run on the Linux box, and make sure you can access them from other machines on the local network. That way, you will know if you have any firewall issues, or configuration problems. One of the first services I would configure is ssh.
Configure the Linksys box to forward incomming ssh connections to the Linux box. Try connecting from a remote host. Is it working? If not, check the logs on the Linux box to see if the connection made it that far. If not, double check the Linksys box to make sure the changes are there. I have noticed that some routers will show the changes when using Firefox, but if you refresh the page, they didn't take.
As far as the mode of the modem and router, I would let the modem handle PPPoE, and run the Linksys box set for a dynamic IP WAN connection. But this is more my prefference then anything else. You should be able to set it up, and make it work ether way.
