Hello,
We're using ASA 5510, and the only setting on it is NAT. It worked well until one day our boss found that he could not open www.amazon.com to purchase his kid's gift. He put www.amazon.com to IE 7 address bar and press ENTER, and then it's connecting all the time but showed nothing. I made several tests. The result is that with IE, Amazon website does not show up, but with Google Chrome it is no problem. So far only Amazon website has this problem. Are we hitting some bug?
