This has been bugging me for over a year now, but have never got the chance to look into it properly.
I have lots of PIX 501E's that I use as VPN terminations at some of my clinics. When logging into the PIX's(PDM), I always get prompted for a username and password, twice, no matter what. I had an initial thought it was something to do with the self-signed-certificate.
Does anyone have any idea why?
