Local Networking Limitations

Each emulator instance runs behind a virtual router, but unlike an actual device connected to a physical router, the emulated device doesn't have access to a physical network. Instead it runs as part of a normal application on your development machine. This means that it is subject to the same networking limitations as other applications on your machine:

where <protocol> is either tcp or udp, and <host-port> and <guest-port> sets the mapping between your own machine and the emulated system, respectively.

For example, the following command sets up a redirection that will handle all incoming TCP connections to your host (development) machine on 127.0.0.1:5000 and will pass them through to the emulated system's 10.0.2.15:6000.:
