By default, there is no specific range. WebRTC will of-course need to access
external resource like STUN or in worst cases TURN servers, your signalling will
likely need HTTP on port 80/443, but ICE protocol will try and manage punching a
whole through your firewall assuming it's configured adequately (automatically
open UDP socket return port).

If you still need to control the range, you'll have to get access to the ICE
agent, and configure it, see nice_agent_set_port_range().
