     1  While btcd is highly configurable when it comes to the network configuration,
     2  the following is intended to be a quick reference for the default ports used so
     3  port forwarding can be configured as required.
     4  
     5  btcd provides a `--upnp` flag which can be used to automatically map the bitcoin
     6  peer-to-peer listening port if your router supports UPnP.  If your router does
     7  not support UPnP, or you don't wish to use it, please note that only the bitcoin
     8  peer-to-peer port should be forwarded unless you specifically want to allow RPC
     9  access to your btcd from external sources such as in more advanced network
    10  configurations.
