Is there a way I can spoof my local IP when testing nginx’s geoip  
plugin? I’m running a VM which has a static IP on my local network which  
runs a development version of my app sitting behind nginx. I need to  
test that the right geoip headers are being passed to my app, but since  
I’m on a local network my ip isn’t set in the geoip.dat file.

You shoul built nginx --with-http\_realip\_module, then add trusted client  
address in the confguration:

```
 set_real_ip_from 127.0.0.1;

```

and make requests with the header line:

X-Real-IP: 1.1.1.1
