It’s a shame that I can’t set a ‘deny by IP address’ rule in my router, but sadly I can’t.
Last week I did manage (don’t ask) to create a port-based rule in my router. The rule automatically rejects any request to access a specific list of ports.
So the only requests that the NAS (in its role as secondary firewall) has to process now are port 80 (and other common http-based) requests.
For the last week the CPU utilisation on the NAS has firmly remained steady in the 7-15% band.
So is that it?
Have I made hosting in to a trouble-free zone?
