Suggest new features and other improvements for GlassWire.- Port Blocking, I assume there must be some reason as to why it isnt available from the start. However, if possible and ideally setup in a way you could block ports via listing of TCP/UDP listings of both high level (1-1023 & 1024 up to 49,xxx). Further more if you have the software on multiple machines with the remote client settings in place it would also block for those attached to the account license. That would be KILLER!
I think they are working on port blocking. It may come out on their next update, not sure. 
If only 
We can hope…I just wish someone would maybe, give light to the reasons as to WHY they have not yet. Like I said In the OP I think there must be a reason this far as why they havent yet.
They Have a pretty heavy load on other issues. I’m pretty sure they will get to it as soon as possible. Just have to be patient.
