I have a working WiFi network at home with 3 APs (long house). All of the APs are locked down with WEP and MAC address lists. I want to add an AP that is open to let visitors access the DSL line, but not let them have access to the computers behind the firewall.
I have a DSL connection with a Wireless router connected to the DSL modem (on the WAN side) and a wired network (on the LAN side) to three computers and to the other APs. The wireless router provides the NAT and port forwarding to one of the computers where I host my web and FTP sites.
I was thinking that I could add a new router between the wireless router and the DSL modem and create another NATed region where the open AP would go. I'm concerned that this will break the web hosting I'm doing and will kill the DDNS.
Does anyone have any experience with doing this?
Thanks alot!
