Setting up your router for port forwarding

I'm writing this to help out future novice users trying to set up OpenWebRX on a Raspberry Pi 2.

If you run your receiver from your home internet connection, it is likely that your machine is behind the NAT and firewall implemented in your router. It is a box like this:

By default, incoming TCP connections from the Internet are dropped by SOHO routers, so others outside your LAN will not be able to connect to your receiver.

You will have to set up port forwarding at the admin page of the router, to forward the appropriate TCP connection requests coming from the Internet to the computer running OpenWebRX.

There are good guides on how to do that:

• portforward.com has step-by-step guides for many routers.
• There is a general explanation on howtogeek.com.

OpenWebRX runs on TCP port 8073 by default.
