I have hooked up a Wireless AP into the Optional Port setup as DMZ on the SA 540. My goal is to provide internet access to wireless guest users without giving them access to the entire LAN. The internet access for the wireless guest users is painfully slow. It takes 5 minutes to access Google. Has anybody else had issues with slowness. I am able to successfully ping websites and retrieve their IP address, but it won't connect to any websites via web browsers. Just to humor myself, I configured firewall rules to allow DMZ full access to the LAN and WAN. I am still having the same results. Any thoughts and suggestions?
