Hi,
the only features for securing the web interface as I found are setting a password --webservice-password=<pw>
and setting a different port --webservice-port=<port>
.
What I want is to restrict the access to a single IP address. On ubuntu this is really easy with this command:
iptables -A INPUT -p tcp --dport 8200 ! -s 1.2.3.4 -j DROP
