The execution context for Network Address Translation (NAT).

Required Methods

fn get_local_addr_for_remote( &mut self, device_id: &Self::DeviceId, remote: Option<SpecifiedAddr<I::Addr>>, ) -> Option<Self::AddressId>

Returns the best local address for communicating with the remote.

fn get_address_id( &mut self, device_id: &Self::DeviceId, addr: IpDeviceAddr<I::Addr>, ) -> Option<Self::AddressId>

Returns a strongly-held reference to the provided address, if it is assigned to the specified device.
