When using Cloudflare Tunnel, you generally don't need to open any specific ports on your server directly. Cloudflare handles the necessary port communication. However, it is important that the necessary ports for WebRTC (typically UDP ports, such as 3478 for STUN/TURN servers) are allowed on the server's firewall and that you configure your tunnel to allow traffic on those ports (though this is often handled transparently by Cloudflare).
