Hello There,

I have currently a Qwest DSL modem (Actiontec GT701-WG). I also have a block of 5 static IP's which are all in use. I currently am not using a router other than the DSL modem. I have more PC's, laptops that
need to be connected via DHCP. But per Qwest
I was told that static IP mode and DHCP could
not both be used concurrently. I tried adding a router to the equation but the DSL modem would not work with the router. Essentially I need to run static and local IP's together with DHCP. Any thoughts?

When using a router, the router get's the static ip.
All clients can have a dynamic ip via DHCP from the router, e.g. 192.168.0.x.
Theoretically, you can connect 253 clients to that router. Practically, the routers normally have only 4 ports an must be extendet by connecting another switch to that router.

So if all of your clients are acting as a workstation and do not provide any services through the internet, all clients can have dynamic ip addresses.

Assuming the router has a private IP 192.168.0.1:
The client should have:
IP address: 192.168.0.x (where x is from 2 to 254)
Subnet: 255.255.255.0
Gateway: 192.168.0.1 (the routers address)
DNS: 192.168.0.1 (also the routers address)

The routers public interface (WAN interface) must be configured with one of your static ip addresses, you got from your ISP.
