# Relay ports (open these UDP ports in the firewall). With "Hide my IP
# address" on, everyone relays: each person holds one allocation, and one
# port, per other person in the room. The app's cap of 60 people in rooms of
# up to 8 needs at most 60 x 7 = 420. If you change MAX_PEOPLE or
# MAX_CONNECTIONS, keep these in step.

# Each person gets their own TURN username from the app; 7 others plus a
# little slack for reconnects. The total matches the app's limits above.
