I'm trying to help a small museum set up open wireless inside their building so tourists can use it in the summer time. They currently have a bunch of computers that the employees use connected to a simple little D-Link router. Some of them are wireless and some are wired. They use MAC filtering so only their computers can connect to the router which is good because they share the My Documents folders of all the machines on the network. They want to give tourists free wireless internet access but NOT allow them to see the computers on the network WITHOUT having the mess with any settings on their computers. This will have to be completely up to a piece of hardware that will not have access to their network, just the web. They have a spare LinksysWRT54G ver.2 that they've never used and I have a Netgear WPN824 v2 I'm willing to give them if they need it. I was messing with the WRT54G this summer and put the Sveasoft Alchemy-v1.0 v220.127.116.11 sv firmware on it just for fun but I can always put the standard Linksys firmware on it if I need to. QUESTION? Can I plug a router into their current router and have the new router NOT have access to the internal network BUT have access to the internet? I just tried it here at home with the WRT54G by plugging it from my router to port 1 of the Linksys and I connected to the internet and the computers on the network didn't show up at all. Is it THAT easy? I would have thought that I would need to plug it into the port labeled "internet" but that doesn't do anything. Am I just lucky? Does it work only because I'm using the Sveasoft Alchemy-v1.0 v18.104.22.168 sv firmware or would it work just as well with the Linksys firmware. If they have to buy different hardware like a "real" access point they don't mind as long as it doesn't mean messing with the computers.
