Hello,

I am facing the same issue. Could you please provide the exact steps to log the 
ACTUAL IP of the user?

Thanks a ton!

Thanks for your help.
It works with the following
 internalProxies="127\.\d+\.\d+\.\d+|10\.\d+\.\d+\.\d+"

127... - for nginx running on the same server as Guacamole
10... - AWS private network

Hi all,

the remote ip registration only worked when I put the options below in 
server.xml

-------
        <Valve className="org.apache.catalina.valves.RemoteIpValve"
               internalProxies="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1"
               remoteIpHeader="x-forwarded-for"
               remoteIpProxiesHeader="x-forwarded-by"
               protocolHeader="x-forwarded-proto" />

        <Valve className="org.apache.catalina.valves.AccessLogValve" 
directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="combined" requestAttributesEnabled="true" />

Att,
Henri.

What private subnet applies to your ELB?

ELB is in the same subnet as the EC2 instance where Guacamole is installed.


Presumably the ELB is not running on the localhost (127.0.0.1), so I suspect 
that you need the actual IP address(es) and/or subnets of the ELB placed into 
the "internalProxies" property in this valve.
