I have an ASA 5540 with 3 interfaces
I have a windows server in the dmz that has outlook client installed that connects to my exchange server on the inside and I am allowing the following protocols between the two machines:
high port 1024 - 1500
everything works however maybe every third the time the client opens the client says is can not contact the server and to click retry, when I click retry it connects fine.
I have opened up the rule for IP but still the same problem. I have done a packet capture between the 2 hosts which I have attached and have broken down the capture to a succesfull connection and an interputed connection.
when they connect the server directly to the inside of the network and connect to exchange they never get prompted to retry.
there is no inspect configured on the firewall.
anyone got any ideas?
