Proxy_protocol, how to check protocol or port (not only remote IP)

Hello:

I am using proxy_protocol at Nginx along with TCP/TCP-SSL ELB at AWS.

Client address specified in the PROXY protocol header is now saved in the $proxy_protocol_addr variable and can be used in the realip module. That is great.

But programmers use to check connection along with php variable $_SERVER["HTTP_X_FORWARDED_PORT"].

ELB proxy_protocol is sending this information inside the headers... I can look for it at headers using tcpdump:

...x..PD .....2P.9..W..PROXY TCP4 77.224.111.207 192.168.10.182 51449 443

At the end, you may see proxy_protocol is sending out this port information.

Is nginx suppossed to include this port information into a proxy_protocol_* variable?

I really need to know what is the original Port used at PHP... I have had a look at google/nginx and I think developers did include only the remote IP, but not the port.

Any ideas?

Thanks so much.
