what I'm trying to achieve here is to be able to give my student neighbor access to the internet using the wireless side of my DSL router but I wouldn't like to have to setup encryption/privacy in any of my intranet wired XP/Ubuntu based workstations or my NAS
I think this should be easy to setup but the solution has been eluding me for the last two weeks. I tried/intended to use firewall based solutions like ipcop pfsense and a few others but it got too complicated very soon, somehow whenever the router gets the WAP TKIP key (which I provided him along with the SSID name) it automatically lets the user access my wired network and workgroup.
of course, I took all my files offline and cleared the shared folders, but I still want to be able to share without having to disconnect my fileserver . I think two separate networks or some kind of "network splitter" prohibiting the traffic between my computers and the wireless network should do the job . unfortunately, I don't see how to do it in a inexpensive way or spending just a little bit.
yes I know about fonera devices and wrtg54g linux based devices. all I have is a switch , the router and a few pci wireless NICs and a spare computer .
+1 for using subnets. i've never thought of that before. – Ian Boyd – 2010-07-30T20:36:19.667
If your DSL router does not have multiple ethernet ports (most probably won't), you can put your 'private' network hanging off of your 'wifi' network. This will put the three networks inline and should accomplish what you want: internet -> DSL Router -> Wifi Rotuer -> private router – Peter – 2009-12-28T02:00:34.503
