The $server_port variable is not expected to be changed by the
realip module. If you see it changed - you may want to provide
more details.

The original question you are answering to, as asked two years
ago, was about $remote_port. The $remote_port is somewhat
expected to be cleared as long as the address of the client as
seen in the header configured only contains the address itself,
and not the port. And this is usually the case. Starting with
nginx 1.11.0, the realip module is able to recognize and use
addresses with ports from the header, see CHANGES:

*) Feature: the ngx_http_realip_module is now able to set the client
port in addition to the address.

But it is not something usually configured and/or available from
normal proxies in the X-Forwarded-For header.
