Port Neches, TX | Static IPs-- A quick How-to With a lot of folks upgrading to static IPs I'm seeing a lot of requests on how to set them up. There's a couple of different ways to do this, depending on what someone is wanting to do.
For the sake of simplicity, I'm going to use a configuration that would take the majority of DSL/CABLE routers that are available today. These typically use a bridge modem as the primary DSL interface. If someone is using a modem/router combo such as a Cayman 3220 or Efficient 5861 the the DSL modem shown is not needed(although it will require a little different setup)
This first example shows a true Static setup where each individual computer/server has it's own WAN IP. This is a basic setup and each machine is completely on the DMZ and each is a seperate connection on the Internet.

Port Neches, TX | This next example shows what the majority of customers have in place. The DSL router has a single WAN IP and by using NAT, can share that single connection with numerous machines. The router will perform basic firewall functions by assigning Class C non-routable IPs to the client machines.
If someone wants to use Internet servers, they will have to assign Pinholes, or in case of advanced routers port/IP mapping, to allow these LAN machines to seem like they're on the Internet.
This typical setup will allow up to 253 computers to share a single connection.

This next example shows a more advanced configuration.
Using a hub or switch, the end user can have simultaneous WAN-LAN connections.
The WAN connections will each have a true WAN IP and will again be straight on the DMZ. It's highly recommended that each be running a firewall to prevent intrusion.
The LAN connection will again use a DSL router and will share it's single connection to other LAN machines using NAT.
This example will save the problems of having to setup pinhole or port/IP mapping but again, THE WAN MACHINES ARE DIRECTLY ON THE INTERNET, so use caution and a good firewall!
Hope all this helps.
