You will need to open at least UDP port 19302 for communication with the
STUN server, but even after that there is a peer-to-peer WebRTC
connection that I believe just uses random ephemeral UDP ports.

There's no way to restrict to port selection. Snowflake isn't meant to
work in an environment where UDP is blocked by default; that would
require a different set of design tradeoffs. So don't feel obliged to
try to make it work with your local firewall. Thanks for giving it a
