Public Wifi on a private LAN
Posted on 2012-03-23
I'm sure this is simple, but so far I have not had success. I have a WRT54G loaded with DD-WRT and a Netgear FVX538 router. The Netgear (192.168.1.1) is connected to my internet and is a DHCP server. I want to be able to provide wireless internet through the Linksys without the possibility of probing to the 1.1 network where my personal computers are.
What I have done: set up DD-WRT as 2.1 with a static IP on the WAN (1.17) and connected the Internet port to a LAN port on the Netgear. It works; it is acting as a DHCP server on the 2.1 network and I can access the internet; however, I can also type in a 1.xx address and open a web page on one of those computers. I can't have that. The Linksys (clients will always be wireless) needs all traffic to go to-from the internet only. I don't even want a ping to a 1.xx address to respond.
What am I missing here?
