nginx using custom port -

i have installed lemp on ubuntu. using port 4738 nginx listener. works fine. can access page 123.123.123.123:4738.

i want rid of port in url. how it? have read many answers on , tried didn't work me. following example:

port_in_redirect off;      location / {     proxy_pass http://123.123.123.123:4738;     }

and

proxy_redirect http://123.123.123.123 http://123.123.123.123:4738; port_in_redirect off;

if you're not using default port protocol, have have port in url. have listen on port 80 if expect not have port in http url.

configure server listen on port 80.
