I don't think that X-Forwarded-Port is a good idea:

- where seen, it's used for other purposes - to indicate _server_ 
  port of a load balancer, not client port;

- it should be easily possible to use the same header to pass to 
  both addresses and ports; this is how it is defined in RFC 
  7239 for the Forwarded header, and we can use something similar at 
  least for custom headers.
