Yes, however we recommend using the following procedure is the only way you can do so without a block of IP addresses. The example below is for instances where you have multiple public IP addresses that are not in block form. For our example the ISP has given us 3 Public IP addresses. One goes to the FTP server, Web Server, and the Router. You can setup the router for whomever your ISP is. If you have a dynamic IP address and you're unsure on the setup, please see the article on setting up the router with a static IP address. If you have a static IP address please our article on setting up static IP addresses with the router, and it will describe how to setup the router with a static IP address. Once the router is setup, it will provide the 3 PC's (In our example) with internet access. The remaining two public IP addresses should be assigned to the WEB Server and the FTP server. Note - The Web and FTP servers will not be on the Local Area Network of PC-1, PC-2, and PC.

How do i hook up my router?


There are several ways to do this, depending on how your network is configured.

Generally, if you have only one router - you connect the network jack of your cable modem or DSL modem to the WAN ("wide area network" or "internet") jack of the router with a CAT 5 network cable or jumper. Each computer's network jack would be connected to one of the router's (4) LAN ("local area network" or "home network") jacks labeled 1, 2, 3, & 4.

steve_con_12.jpg
In the picture above, the left most jack (WAN) of the router connects to the cable or DSL modem. The "LAN" jacks labeled "1, 2, 3 & 4" connect to each computer's network jack in your home.

The above would change if you are simply adding this router to extend an existing network. You'd likely be using this router as a switch, and leaving the routing duties to the main router. Over simplified, all the CAT 5 network cables would be connected to the 4 LAN jacks. There would be no connection to the router's WAN jack because the output of the first router provides only private IP addresses used in YOUR location. The internet IP address from your ISP is used only at the first router so that your entire home has the single IP address. The WAN jack is for internet addresses only - and the LAN jacks are for local / private addresses in your home only.

Have a look at the LinkSys web site for help configuring your particular model router, or reply with the model and version here.

I hope this helps & good luck. Please rate my reply - thanks!

Dear Assistants I have a router linksys compact wirless - g broadband router. model number WRT 54GC ver. 2 and i have a problem with it I cant find anywhere the WAN MAC Adress of the Linksys What to do???...


The Linksys has a device MAC address and the router issues IP addresses to the computers that are connected to it.
There is no WAN MAC address. Your ISP issues to your cable or DSL modem an unique IP address and you connect this modem into the WAN port on the Linksys router.
You enter the routers configuration address -
http://192.168.1.1
and login and configure the router.

WAP connecting to another WAP


On the D-Link WAN page, change IP Address to static and give it an address about 30 away from both the Hawking and the Linksys. On the DHCP page, disable DHCP.

In a multiple router network such as yours, you can only have ONE real router. The others have to be disabled as routers. Disable thier DHCP and give them static addresses that are all at leat 10? or more from each other. Wireless should all be the same setup. The on;y exception is the SSID which can be slightly different to know which wireless you are on.

When dealing with a router there are multiple IP address scenarios, on the internet service provider's (ISP) side you can have either a static or dynamic IP address. I believe most routers by default are set to accept a dynamic IP address from the ISP. Where the ISP permits the router can also assign IP addresses to each device that attaches to it allowing a single ISP connection to be shared by multiple computers. This is also generally the default for routers purchased for home use and the wireless adapters also accept the dynamic IP assignment from the Router. With the logical discussion out of the way I believe you wish to discuss the physical connections to be established. Again this is a generic discussion not knowing your specific environment. port types - I will refer to phone ports (technically RJ-11 either two or 4 wires (these cables plug snugly into phone jacks and modem connectors) and ethernet ports (technically RJ-45 which are 8 wires and to big to fit in phone and modem ports) First you have a connection provided by the ISP for DSL this is your phone line where filters are attached to your voice phones and an unfiltered phone connection goes into the DSL modem's phone port often with an ethernet port. If you have cable generally the cable company provides a connection to a cable modem which has an ethernet or other port to connect to your system. The ethernet port generally connects to the wan port (generally separate) of your wrt54g router with an ethernet cable. Computers can be attached to the wrt54g router using the 4 ethernet ports in a group provided they have an ethernet port too. Wireless cards connect to the wrt54g router through radio waves and with antennas on the router and often internal to the wireless adapter (often embedded in a notebook computer today). These details are enclosed with your ISP's instructions and the Linksys router instructions often with pictures to help the explanation.
