Is this an exotic or common feature in firewalls?
Say you have a port forwarding rule in place to allow incoming packets to get to a device on the LAN.
But that can open you up to malicious attacks on that port against that device the port forwarding is set up for.
So>>>> in (some / most / all / none?) firewalls, you can set it up so only specific public IPs from outside (certain IPs / a range of IPs?) can get in via the port?
Like port forward 8080 to 192.168.1.33 ONLY IF the request from the outside is coming from 220.127.116.11/24 or just 18.104.22.168 ?
