Question : Guest Wireless Network

We have a client that wants to setup a wireless network so that their clients can connect to when they come in to the waiting room. The office already has 3 wireless routers (access points) that are connected to the network on the 10.xx.xx.xx. This network is not broadcasting the SSID and is secured with a password only we know.

My questions are: Can we use the 3 existing routers to setup a guest connection? Can this connection be off of the 10.xx.xx.xx network and be on a 192.168.xx.xx network? We do not want guests in anyway to see the 10.xx.xx.xx network. If this can be done how should we do it? If it cannot be done, how do you recommend we set up a guest network.

Note that the routers are Linksys WRT54G. Our ISP has given us a WAN address. (not sure if that should be used or not).

Thanks for your help :)

Answer : Guest Wireless Network

Oh, well, since you have a sonicwall, this get MUCH easier.  I'm going to change things up for you if you don't mind and offer a new suggestion.

First, what's the model on your sonicwall?

Here's what I've done in the past with the sonicwall.  Configure an available interface or OPT port.  Connect the guest wireless router to the interface.  Configure the firewall on the sonicwall to not allow the new interface access to your LAN and give them access to the Internet.

                                           --LAN
T-1 router <> sonicwall < 
                                           --OPT <> guest wireless router
