realip disabled if header contains port

[foxgab]

hello,

i found http_realip_module doesn't work if the realip_header contains client
port.
my config is like bellow:
http {
    real_ip_header      X-Real-IP;
    set_real_ip_from    0.0.0.0/0;
    server {...}
}

the X-Real-IP header in the request is:
X-Real-IP: 123.123.123.123

but the $remote_addr variable in the log turn out to be the address of last
hop proxy.
is anything wrong?
