Wow you are right that is a mouthful, I might have lost you, but why don’t you just set up the router to provide all IP addressed to devices via DHCP, forget the sharing the connection through computers, this should be easier that having to deal with the rest.
DO you get a static IP from your ISP, or is it dynamic?
Then all the computers will be on the same network, by default 192.168.1.x on linksys routers, but you can change that if you want to.
Hope this helps at least a little.
Hi, I have a network in my home a network like the network you wish.
Here is the configuration.
I connect the Wireless G Router directly to the internet network (an internet provider), so I have used the WAN connexion in the Router to connect my network to internet.
The internet provider give me an ip address like 192.168.62.30 in this case they give me an fixed IP, sometimes they give you an IP generated by a DHCP, so you must investigate what kind of address you had.
After set the WAN or internet conection in your Router, you have to create your own network, follow this steps.
Define you network, you can use 192.168.2.X (your network is 192.168.2 ).
Router LAN — IP 192.168.2.1 this is your (Default Gateway).
Disable the Automatic DHCP in the Router configuration.
Fisrt PC (can by anyone).
IP address – 192.168.2.2
subnet Mask – 255.255.255.0
Default Gateway 192.168.2.1
DNS (the IP the provider give you)
DNS (same as previous)
Repeat the process with the other PC’s, you must change the IP address for the PC 192.168.2.3, 192.168.2.4, 192.168.2.5,…….
Your problem is that you are using some IP that the provider has using, so yo must create your own network and connect your network to internet through yor router, using the router as a gateway.
After that you can set a wireless network password and enable the router DHCP property to give automatic access to you network to the people you want.
If you think that you need more help, write it. I will be following this question.
