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 TCP2) 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
