NatResolver

Enum NatResolver 

Source
pub enum NatResolver {
    Any,
    Upnp,
    PublicIp,
    ExternalIp(IpAddr),
    ExternalAddr(String),
    NetIf,
    None,
}
Expand description

All builtin resolvers.

Variants§

§

Any

Resolve with any available resolver.

§

Upnp

Resolve external IP via UPnP.

§

PublicIp

Resolve external IP via a network request.

§

ExternalIp(IpAddr)

Use the given IpAddr

§

ExternalAddr(String)

Use the given domain name as the external address to expose to peers. This is behaving essentially the same as NatResolver::ExternalIp, but supports domain names. Domain names are resolved to IP addresses using the OS’s resolver. The first IP address found is used. This may be useful in docker bridge networks where containers are usually queried by DNS instead of direct IP addresses. Note: the domain shouldn’t include a port number. Only the IP address is resolved.

§

NetIf

Resolve external IP via the network interface.

§

None

Resolve nothing

Implementations§

Source§

impl NatResolver

Source

pub async fn external_addr(self) -> Option<IpAddr>

Attempts to produce an IP address (best effort).

Source

pub fn as_external_ip(self, port: u16) -> Option<IpAddr>

Returns the fixed ip, if it is NatResolver::ExternalIp or NatResolver::ExternalAddr.

In the case of NatResolver::ExternalAddr, it will return the first IP address found for the domain.
