I'm trying to set the value of set_real_ip_from from a variable but I'm getting an error.

NGINX Config:

set $frontendIP "104.22.100.4/32";
set_real_ip_from 103.21.244.0/22;
set_real_ip_from 103.22.200.0/22;
set_real_ip_from $frontendIP;

Error:

nginx: [emerg] host not found in set_real_ip_from "$frontendIP"

The problem is not in setting the variable, but set_real_ip_from returning an error.

Does this answer your question? nginx set variable in location – AlexD Jan 03 '22 at 12:29

@AlexD, the problem isn't in setting the variable but set_real_ip_from isn't taking the variable and returning an error. – Tailer Jan 03 '22 at 13:25
