Hello,
what are the minimum ports to open for public if I want to use talk from external clients (not behind my nat, users and guests)?
I installed nc-hpb and coturn on two different hosts. They can reach each other.
Nextcloud is in a different net but nc-hpb and Nextcloud can reach each other. All are behind my nat. Turnserver has all private ranges blocked except my nc-hpb IP.
I guess its safe to open nc-hpb signaling port (8080) if secured with SSL?
Its safe to open Turnserver port 3478 if all private ranges blocked?
Are there any security considerations?
Any hardening I should do?
Thanks
