Subject Re: Web Server HTTP Header Internal IP Disclosure SOLR port

Yea, it really won't work to tunnel Admin UI, it needs to see the actual
IP/host names, so some kind of Socks or VPN would need to be used.
Anyway, you can always set the HOST ( property for each
host to FQDN instead of IP, in which case those names will be used in
clusterstate and also in UI, which is more human friendly than IPs.

But the reporter will have to elaborate further on this. Exposing the hostname
or IP of a Solr node that you as a client (or Admin UI) needs to talk to,
is definitely necessary and by design.
