Hi. I published Horizon to outside using a simple port forwarder. Now, users use 10.162.148.50:8000 to connect to horizon. It works fine.

The problem is when they want to connect instance's console, they cannot connect to "controller:6080". In fact, they cannot resolve "controller" name. How can I make horizon to connect to "10.162.148.50:6080" instead of "controller:6080"?

I know two possible solutions are to configure DNS server or hosts file for clients who want to connect to horizon. But we don't have permissions to configure DNS server, and also manually configuring hosts file for every client is very difficult.

What do you suggest? Is this anyway to configure horizon to make the requests to 10.162.148.50:6080 instead of controller:6080? However, in this way, administrators who directly work from the local network cannot use VNC, since they are not in 10.162.148.0/24 network.

Thanks.
