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.
Thanks for your help!!
