"SketchUp needs access on the following ports: 80, 8080, 443.
For network licenses SketchUp also needs ports 5053 and 50530."
I see port 80 open, nothing else. If I can get them to open the rest, will it still work? (Bentley customer otherwise, so familiar with the corporate push-along on otherwise perfectly working products)
No idea. At work we had a network license (first the local license folder type and then the Internet-based one) before the firm was acquired by its current owner.
