do both license server daemon ports need to be opened?

DrewDowling

ArcGIS License manager has 2 daemon, Sever and vendor. I have always set the Server port to something in the range of 27000 - 27009 and opened up the servers firewall. I never remember having to set the vendor daemon port before.

We recently moved to ArcGIS Pro and named users. We want to move our license server into a DMZ and open up port 27000 so users can use ArcGIS Pro while working remotely.

Will we have to set the vendor daemon port and open up this port as well?

In short, yes you will need to expose both the License Manager Server and Vendor daemons for your users to borrow licenses successfully.
