Hi, I have a PIX 501 with software version 6.3. This PIX is configured to authenticate user for all tcp traffic. The idle timeout is 8 hours. But from 2 days ago, it keeps ask for username and password for authenticated users time to time (every 5-30 minutes). This pix is configured with a url-filter, and it lose connection with the n2h2 server, But I don't think this is the problem since the pix is configured to allow access when n2h2 is not accessable.
Thank you for your reply, I have a absolute timeout for 10 hours. I found an other problem may be the real reason: the pix 501 reboot by itself sometime. I am not sure if this is the reason. But I disabled the authentication for now to let users happy.
