Anyone out there familiar with using HA Proxy for a load balancer? We recently began using a load balancer with a public IP routing to our internal JSS servers with an internal IP. The problem we have is the internal IP is now showing for just about every iOS and OS X device. we have followed just about every suggestion on the boards.



Ensured Apache Tomcat settings in the JSS was set to Enable Remote IP Valve,



Modified the Server.xml to contain
<Valve
className="org.apache.catalina.valves.RemoteIpValve"
internalProxies="x.x.x.x"
trustedProxies="x.x.x.x"
remoteIpHeader="x-forwarded-for"
remoteIpProxiesHeader="x-forwarded-by"
protocolHeader="x-forwarded-proto"/>



setting the "x.x.x.x" to both the internal IP and the external IP.



We have done a hybrid of all of the above.



Any assistance would be greatly appreciated.

We found it quite helpful to include the forwardfor and httpclose options for our jss backend in our haproxy configuration:



backend jss-cluster

    balance source

    option forwardfor

    option httpclose

    option httpchk

    server jss-node-0 jss-node-0.acme.http:443 ssl ca-file /etc/ssl/certs/ACMErootCA.pem verify required check

    server jss-node-1 [...]

    [...]


Our Tomcat server.xml only requires



 <Valve 

          className="org.apache.catalina.valves.RemoteIpValve"

          internalProxies="1.2.3.4"

      />


to make the magic happen.

@localhorst Thanks for the insight,



Do you have Enable Proxy Port enabled? if so what port are you using? What scheme?



Thanks, load balancing is new to us and we need to get this issue resolved.

Hi @mradams,



Server.xml should at least contain the following options:



        <Valve className="org.apache.catalina.valves.RemoteIpValve"

               remoteIpHeader="x-forwarded-for"

               proxiesHeader="x-forwarded-by"

               protocolHeader="x-forwarded-proto" />


And do not forget to add the jvmRoute:



    <Engine name="Catalina" defaultHost="localhost" jvmRoute="jss1">


We have used port 8080 (directly from HAProxy) and now use 8009 (via HAProxy and Apache Proxy).
