Public IP Address on LAN Port

Hi All,
I have been scouring the internet for answers to no avail.

What I want to do is use my public IP address on my modem through the LAN port on the modem. So I want my ADSL modem to plug into my phone line, get a public IP address, and then that public IP address is the IP address that I get when I plug a router (or PC) into the LAN port of the modem. At the moment I get a private IP address (class C) from the modem. This is mainly to use servers behind my network, and I don't want to muck around with port forwarding.

I am using a Linksys AG300. What would I be looking for?

Thanks,
Michael

 

Only one device can have the WAN IP. Your router gets it.
No way around it unless you have a block of WAN IPs.
