map_port ?bind_addr ?broadcast_addr ?timeout ?single_search_timeout ?local_addr ?lease_duration ~description ~local_port ~external_port ~any_net_port () will look for the gateway and ask for a redirection on external_port to local_port. If any_net_port is true, a port will be randomly selected by the gateway, otherwise it will use external_port. It returns the current machine address and the external port that serves for redirection.

bind_addr, broadcast_addr, timeout and single_search_timeout are UPNP/IGD discovery parameters, default parameters should be enough and should be changed carefully (see documentation of `rust_igd_next`).

local_addr is the local network address sent to the gateway for redirection. map_port can find it automatically, but it can be overridden in case it didn't find it automatically.

lease_duration is the duration in seconds the redirection is kept by the gateway. `0` by default, meaning either an infinite duration for UPNP/IGD v1 or 604800 seconds (two weeks) with UPNP/IGD v2.
