Recently support helped me resolve this issue:
However, now I want to allow a specific IP address through this port block.
We want to allow a single laptop to RDP into a group of computers but no others.
I created this rule to allow it and placed it above the priority list for the rule that blocks incoming RDP.
However, this does not allow the computer in question access. I also tried a global allow rule above a deny rule and the deny rule seems to take priority. Is there anyway to accomplish this task with Bitdefender?
