We have a single gateway acting as a perimeter firewall and a maestro setup with 1 security group. Both are being managed by a Single SMS. Our testing aims to access Facebook but block Facebook-Posting. This requires HTTPS inspection and we enabled it on both gateway and maestro.
Behind the gateway we have a test PC and it is working properly. Facebook posting is blocked, However, on the test PC behind Maestro, it's not working. Please see attached images for reference.
Anyone experienced this before? Thanks in advance.
