Grav and firewall rules

Hello,

I am configuring a Grav website on a system which has no unlimited access to the internet.
For the moment I am not even able to download the plgins via command line gpm since our company firewall is blocking access to the grav sites.

Is there a list of sites which has to be accessible from our grav web server in order to:

• update grav
• install plugins
• install themes
• accessing the information in the admin dashboard

Is https://getgrav.org sufficient?

Thanks in advance for your help!

Yes, GetGrav.org should be sufficient since the GPM routes through there. GitHub.com is also be advisable, when you need to test out more code and not be bound to Admin/GPM.
