How do I configure my home LAN router (D-Link Dir-882) to accept communication to a LAN IP&port just from one specific WAN IP address only?
I have a port open on my DIR-882 Home LAN router because i routinely access it from a WAN computer using VNC software. However, my home LAN open port gets attacked by people trying to gain access. i have tried changing ports, and changing IP addresses but the attackers keep finding my IP and open port. So, i would like to tell my home LAN DIR-882 Router to only open the specified port for traffic only to&from the WAN IP of the computer i am using. So, from the routers web GUI i selected "Turn ipv4 filtering ON and ALLOW rules listed", and entered the following rule;
Source IP address range: WAN: (i typed in the WAN ip address of the computer i use to access my home computer)
Destination IP address range: LAN: (i typed in the LAN ip of my home computer)
Protocol and port range: ANY: (i typed in the port i want open on my home LAN computer)
Schedule: always enable
.... but then i couldn't browse the internet on the LAN computer.
Any guidance would be appreciated,
ps: the LAN & WAN computers are all iMacs.
