To function properly, Seshboard must communicate with:
Seshboard's backend servers
Cloud servers operated by Twilio (for video communication)
Google Cloud servers (for data storage)
Domains for tools that can be optionally embedded in Seshboard rooms
Below are the domains and ports that must be allowed by your firewall.
1) Seshboard's backend servers
app.seshboard.com 443 TCP
seshboard-prod-1.wl.r.appspot.com 443 TCP
2) Twilio Video
Seshboard uses Twilio Video (a WebRTC video platform) for video communication. Twilio Video needs access to signaling servers on these domains and ports:
global.vss.twilio.com 443 WSS
sdkgw.us1.twilio.com 443 WSS
au1.vss.twilio.com 443 WSS
br1.vss.twilio.com 443 WSS
de1.vss.twilio.com 443 WSS
ie1.vss.twilio.com 443 WSS
in1.vss.twilio.com 443 WSS
jp1.vss.twilio.com 443 WSS
sg1.vss.twilio.com 443 WSS
us1.vss.twilio.com 443 WSS
us2.vss.twilio.com 443 WSS
To handle video streams, Twilio Video also needs UDP traffic to be allowed on ports 10,000 - 60,000 for the following IP address ranges:

3) Google Cloud
Because Google Cloud services are very widely used, it is likely that your firewall already allows connections to these services.
firestore.googleapis.com 443 TCP
securetoken.googleapis.com 443 TCP
firebasestorage.googleapis.com 443 TCP
4) Embedded tools
miro.com 443 TCP
mirostatic.com 443 TCP
www.youtube.com 443 TCP
docs.google.com 443 TCP
