I have looked around a little for this answer but have not found one that fit my problem. I have a small business in which I use DSL. I want to provide wireless access to my clients while they wait in my lobby using that DSL connection which I also use for my internal network. I have a modem/router for the dsl from bellsouth (netopia hardware) which handles my dhcp and is connected to all my wired devices via 2 eight port switches, I don't have a domain (running a simple workgroup) but do have a file server. I also have a linksys wrt300n which I want to use for wireless access. Now I can plug that into one of my switches via a regular port on the wireless AP (not the wan port) and turn off the dhcp on the linksys and the wireless devices show up on my network fine, but I want to isolate them completely so the wireless internet guests don't screw around on my network, but I don't want to get a separate internet line for them. I have tried the AP isolation feature on the linksys but that separates the wireless users from each other, not from the wired guys. A simple solution would be ideal, the wireless users only need internet for browsing the web in the lobby, they don't need any network resources or anything; I just want to protect my wired network. Any ideas or suggestions would be appreciated. Thanks in advance.
