How to limit webrtc UDP connections to a specific port range?

[D1plo1d]

I'm trying to limit webrtc UDP connections to a port range so that they can be NAT port forwarded by users of an IOT device. So far I haven't been able to figure this out, does anyone know how to select a port range for webrtc-rs?

I see in /ice/src/udp_networks.rs:7 that EphemeralUDP supports providing a port range and that looked promising at first but I don't see how I could set that from outside the crate boundary.

This can be configured via SettingEngine::set_udp_network as follows

let mut ephemeral_udp = EphemeralUDP::default();
ephemeral_udp.set_ports(4000, 4050)?;

let mut setting_engine = SettingEngine::default();
setting_engine.set_udp_network(UDPNetwork::Ephemeral(ephemeral_udp));

let api = APIBuilder::new()
    .with_setting_engine(setting_engine)
    .build();

EDIT: Updated to use public API so it actually compiles.

Thanks @k0nserv, that's what I was missing!

For anyone who stumbles onto this issue later, I modified the example a bit to use set_ports because port_min and port_max aren't public:

    let mut ephemeral_udp = EphemeralUDP::default();
    ephemeral_udp.set_ports(4000, 4050)?;

    let mut setting_engine = SettingEngine::default();
    setting_engine.set_udp_network(UDPNetwork::Ephemeral(ephemeral_udp));

    let api = APIBuilder::new()
        .with_setting_engine(setting_engine)
        .build();

Thanks. I updated the answer per your comment, as you can tell I wasn't actually compiling the code :)
