This page provides information on how to connect to evercast.us using firewall access rules. It's intended for networking and IT professionals in your organization.
Evercast is a modern, dynamic application that leverages WebRTC on our own servers as well as the STUN protocol from our provider at Google.
evercast.us
app.evercast.us
*.evercast-webrtc.com
*.evercast.us (required if you are using DAM integrations)
The majority of our traffic will originate from these IP ranges, though occasionally we leverage other AWS-based IP ranges outside of these.
76.76.17.0/24
161.199.67.0/24
TCP port 443 for traffic to app.evercast.us
TCP and UPD ports 3478,20000-25000 for traffic to *.evercast-webrtc.com and occasionally other AWS-based IP ranges
TCP and UDP port 19302 for traffic to stun.l.google.com
For port 19302 above, the google URL uses a lowercase “L” and not a capital “i”.
Firewalls must be configured to allow stun UDP traffic (ingress and egress) to properly establish the connection between clients and the media server.
P2P is required for WebRTC to function.
Path MTU discovery (PMTUD) is required to determine packet MTU size.
If access is still blocked after adding these values to the firewall, we recommend testing by allowing all traffic to the MAC address of the connecting device.
