On the access restriction page I can restrict outgoing wan access for clients on my lan. Is there a way to do this in the opposite direction (restrict incoming connection requests)? I have a NAS acting as a webserver and defined a port forwarding. It looks like some hackers have programmed robots that test vulnerability of webservers. These attempts to hack my server cause it to wake up from sleep, and the harddisc is spinning up. Debugging these wakeups, I found that these attacks mainly come from ips from china. So I'm searching for a solution to limit access to my webserver to known ip ranges from my country. I tried to use some unusual port for my webserver, but then I cannot access it from work. At work we have to use a proxy for internet access (firewall) that only allows port 80 and 443.
