Question to Signal, Skype and Google Hangouts video calls

MPI-AE — Wed, 30 Jan 2019 12:29:31 GMT

Hey guys,

When I want to do a video call with Signal messenger, I need to add two rules:

Rule1:

App: Signal

Service: application default

Rule2:

App: STUN

Service: any

Signal accesses random destination ips on random ports.

Skype and Google Hangouts need those rules:

App: Skype, Google-Hangouts

Service: application default

App: rtp

Service: application default

App: rtcp

Service: application default

As a result I had to add those 3 rules for all 3 apps to work:

App: rtp

Service: application default

App: rtcp

Service: application default

App: STUN

Service: any

Do you experience the same?

@MPI-AE,

I've had a similar issue with Signal needing Stun access, to me Signal should list that it depends on STUN.

As for the Skype and Google-Hangouts question, you should be looking at the Depends-On listing when you are enabling these applications. Skype and Google-Hangouts both have a long list of app-ids that they depend on being allowed to function correctly.
