Please assist i Cisco Firewall FPR 1120 and ever since i put on the network my outgoing emails from Exchange Server 2013 are taking long to be sent out, often queuing at times up to 9 mins. I also have an office 365 protection subscription and my emails are routed through that. My question is do i need to my an exception for the Office protection and if yes, what configuration changes do i have to make?
Thank you for the response, I am not sure how i can do that. My Exchange server IP address is natted to a public address, how will i be able to achieve that? I have attached my Nat Config, hope it helps
Try creating a TRUST rule for incoming & outgoing traffic towards the "Exchg-Private" IP in Access Control Policy and move this rule on top of other rules.
I have a permit rule that allows outside traffic to the Exchange Private host and it is on the top of the access rule. My main concern with the Trust rule is that it over provision. For example i won't be able to inspect the incoming traffic. Doesn't that open up my system
Hi, Is this a new deployment..?? While making the rule action as TRUST we can identify Firepower is queuing the emails or not. When the action is in TRUST try sending emails and see check still the emails are queuing for delivery. This is just for testing after that you can revert the changes.
Wow, i was really surprised that even with the trust configurations, still my mails are still queuing. What can be the problem
