Suggestion for supporting port ranges and WebRTC

[alexis-belmonte]

Hi!

I think it would be great if this image could expose an option to select a range of ports rather than a specific one: a variable like TARGET_PORT_RANGE would have to be defined, and SSL_PORT could simply contain the first port number to map to.

Another feature which would be cool is SSL forwarding for WebRTC.

Very grateful for the existence of this image still, just that I currently have to define a bunch of cloned containers with slightly different ports each time :P

Thanks!
