configuration of reverse proxy on a different host

[dexterdy]

After testing many different configurations, I figured out that the reverse proxy on a different host only works if both the IP address as well as the network mask are present in the config, not only one of the two.

This was not clearly mentioned in the docs, so I am making a pull request.

As an aside, the netmask can be figured out from the cidr notation ip address, so I feel like also specifying the netmask separately should not be needed.
Also, may I suggest to always allow the netmask of whatever networks the machine is on by default, so users ony have to specify the ip addresses and not also the netmasks?

Other than that, this looks like a really promising software suite feature-wise, though usability and docs can be improved.

both the trusted IP addresses and network masks from which the proxy connections originate

This is incorrect. If you specify a network mask there is no need to specify also an IP address.

Ah, in that case this is a bug, I think, because when I tested that, it did not work. I shall try again to make sure that it is not a fluke
