Re: [keycloak-dev] Retrieving client's public IP not working with HTTPS

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 ************; fastcgi_param HTTPS on; location / { add_header X-Cache-Status $upstream_cache_status; add_header X-Real-IP $remote_addr; add_header X-Forwarded-For $remote_addr; add_header X-Forwarded-Proto $scheme; more_set_headers 'Server: ******'; more_clear_headers 'X-Powered-By'; charset UTF-8; proxy_cache ******_cache; proxy_pass https://1.1.1.1:8443/ <https://1.1.1.1:8443/>; }* * ssl on; ssl_certificate /etc/ssl/private/**********.crt; ssl_certificate_key /etc/ssl/private/*************.key; ssl_prefer_server_ciphers on; ssl_dhparam /etc/ssl/***********.pem; ssl_protocols TLSv1.1 TLSv1.2; ssl_stapling on; ssl_session_cache builtin:1000 shared:SSL:10m; add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload"; add_header X-Frame-Options "DENY"; ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';* - *Keycloak config* : * <subsystem xmlns="urn:jboss:domain:undertow:3.0">* * <buffer-cache name="default"/>* * <server name="default-server">* * <http-listener name="default" proxy-address-forwarding="true" socket-binding="http"/>* * <https-listener name="https" security-realm="**********" socket-binding="https"/>* * <host name="default-host" alias="localhost">* * <location name="/" handler="welcome-content"/>* * </host>* * </server>* * <servlet-container name="default">* * <jsp-config/>* * <websockets/>* * </servlet-container>* * <handlers>* * <file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>* * </handlers>* * </subsystem>* 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 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 which is not what I want as I would prefer getting to 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 : *14:24:30,621 INFO [org.jboss.modules] (main) JBoss Modules version 1.5.1.Final* *14:24:30,821 INFO [org.jboss.msc] (main) JBoss MSC version 1.2.6.Final* *14:24:30,888 INFO [org.jboss.as <http://org.jboss.as>] (MSC service thread 1-2) WFLYSRV0049: Keycloak 2.5.0.CR1 (WildFly Core 2.0.10.Final) starting* *14:24:31,597 ERROR [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0055: Caught exception during boot: org.jboss.as.controller.persistence.ConfigurationPersistenceException: WFLYCTL0085: Failed to parse configuration* * at org.jboss.as.controller.persistence.XmlConfigurationPersister.load( XmlConfigurationPersister.java:131)* * at org.jboss.as.server.ServerService.boot(ServerService.java:356)* * at org.jboss.as.controller.AbstractControllerService$1. run(AbstractControllerService.java:299)* * at java.lang.Thread.run(Thread.java:745)* *Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[380,17]* *Message: WFLYCTL0376: Unexpected attribute 'proxy-address-forwarding' encountered.
