Hint on restart after changing network seetings

[margin-auto]

When I change the remote access settings in FAHControl for a client (allowed/denied IP range, password) a restart of the client seems to be necessary for the changes to take effect.
In the corresponding dialog in FAHControl there is no hint on this need. One could assume that after clicking "Save" the changed settings were already applied. It would be great to have a corresponding hint after changing the values in this dialog or an automatic restart of the client.

I use FAHControl 7.5.1 with Ubuntu Linux
