Restricted Network -> What permissions?

Hello!

We've gotten our company network revamped and now its even more restrictive than before, yay!

So currently we cannot use Normcore, as the requests to the normcore-matcher are being denied.

Are there any other services or urls that we need to make accessible besides the matcher?
Coms with NetDep is always a slog so would like to get it all covered the first time.

Thanks in advance!
