Hi Guys.
OK here is the situation. I have one dsl connection , three computers and a wireless router. Computer 1 is used throught a vpn thru and offsite server (on Lan). Computer 2 is connected to other eqiupement at this location (on lan). Computer 3 control cameras throughtout this location (on lan). Multiple credit card machine are being used on this lan also (they process thru the dsl connection). The dsl connection goes into the wireless router and then out to all the machines (yes all machines need access to the internet). I currently have the wireless disabled. I want to offer wireless to customers that use this location but i am concerned about security. I know multiple dsl connections are the best solution, however that is not cost effective. Any ideas? (different subnets?, two routers?)

Yep, I'd use two routers.

Enable the wireless on the one connected directly to the DSL and allow the clients to connect to this one. Configure the second router to be in the DMZ of the primary router so you don't have to configure forwarded ports in both routers. Connect the WAN/Internet connection of the secondary router to one of the LAN ports of the primary router. All the equipment on the secondary router will have the NAT firewall of the router protecting you from access by the wireless stations on the primary router.

I'd consider a primary router with some sort of QoS capability so you can limit the total bandwidth consumed by the wireless clients, they could suck up most of the bandwidth if you don't do anything to stop it.
