Every few months PIX stops passing outside traffic for HTTPS (443) port for Exchange server OWA ( internally it works just fine). When I look at xlate it shows 0 bytes and flags aB. I change rule to port 4343 and it works. After a few weeks I change back to port 443 and it works. I dont understand why it randomly stops working and then randomly works again. Does anyone had same or similar problem ? Thank you.
