Nginx proxy_pass with $remote_addr

Question

I\'m trying to include $remote_addr or $http_remote_addr on my proxy_pass without success.

The rewrite rule works

location ^~ /freegeoip/ {  
  rewri         


        

Answer 1

It seems a bit strange that nginx is failing to resolve the domain name at runtime rather than at configuration time (since the domain name is hard coded). Adding a resolver declaration to the location block usually fixes dns issues experienced at runtime. So your location block might look like:

location ^~ /freegeoip/ {
  #use google as dns
  resolver 8.8.8.8;
  proxy_pass http://freegeoip.net/json/$remote_addr;
}

This solution is based on an article I read a while back - Proxy pass and resolver. Would be worth a read.
