I have an ASA 5512 running 9.4(4).18 here's my issue.
Server A on lan range 10.10.1.0/24.
Server B on lan range 10.10.1.0/24.
From the outside world i can access mydnsname.com and reach services on server B fine. Server B has internet access. Server B can talk to server A and server A can talk to server B.
From server A if i browse to mydnsnme.com it fails. They're both windows server 2012 R2. I've done netstat and can see i get a SYN_SENT from Server A, Server B shows SYN_RECEIVED from the public IP of server A so i know traffic is getting there.
However i can't see any return traffic happening from server B to server A and i'm not sure why. Any hints where to look? Packet tracer shows it should work fine.
