I never tried it with Keycloak, it may or may not work. But you can try to set
on nginx 'set_real_ip_from' with 'real_ip_header'[1].

Dear,
I get an issue to get the wanted behavior when retrieving the client public
IP.
This is the situation :
(all IP's have been anonymized)
- *infrastructure level*:
----------- Reverse Proxy NGINX ----------------------------------- KeyCloak
RP is listening on ports 80 & 443 (80 is redirected to 443)
There is a public certificate signed by some external CA
Nginx redirects to the 8443 (https) of KC (HTTP runs on 8080)
Keycloak is set as standalone server on a Wildfly last version
- *Nginx config*
*server { listen 443; server_name ************;

The situation is that everything is working fine and smooth EXCEPT ... the
fact that under sessions (and moreover for all user activities), the user
IP I see is the one of the reverse proxy !!
As I put in red in the KC config, this is what should do the trick to use
the X-Forwarded-For header value to set the client's IP.
15:07:55,104 WARN [org.keycloak.events] (default task-19)
type=REFRESH_TOKEN_ERROR, realmId=***, clientId=account, userId=null,
ipAddress=2.2.2.2, (...)
When I tried to reach KC on the 8080 (HTTP) listener (so the RP terminates
the SSL connection and the one to KC server is made in HTTP), I got
obviously a whole bunch of warnings and errors due to HTTP -> HTTPS
transport and also a HTTP connection towards the external social identity
providers like Google, FB, etc. ... BUT I got at least the real IP as you
might see hereunder :
15:09:24,068 WARN [org.keycloak.events] (default task-29)
type=LOGIN_ERROR, realmId=*****, clientId=account, userId=null,
ipAddress=191.21.133.234, (...)
So the situation is that I will only get the "real" IP of the client only
if it passes through the HTTP listener of KC (that has the parameter
"proxy-address-forwarding") which is not what I want as I want to reach the
HTTPS listener.
I obviously also tried to add the same parameter (*proxy-address-forwarding
= "true"*) in the HTTPS listener configuration but then, standalone.sh
shows an error and refuses to start :
