Hi, I've got an issue I've been digging into for some time. Every few weeks, one of my users cannot access our own secure website (via WAN or LAN interface) and receives a connection timeout when trying. Changing the IP address of the PC in question gets everything working again. I can't find anywhere in the firewall log (PIX 515e) that shows anything being blocked, and our ACL enables traffic to flow (almost) freely to our DMZ and has never had a problem before. Could it be a DNS issue? from our internal DNS or external?
I have this problem too.
