I have a Linksys router RV082. I have set firewall rules to only allow inbound port 21 from my office 126.96.36.199 [WAN1] (source) to the server 192.168.1.10 (destination) using Access Rules and no traffic is being passed to the server. When I added Forwarding (port range) the FTP works fine, except I can also FTP from my house. Thus the firewall rule is out the door as all inbound 21 traffic is forwarding to the server. At this point I have both firewall rules and port forwarding in effect.
I need to restrict all inbound traffic to the LAN and allow only specific ports to go to the server from my office and nowhere else.
Where did I go wrong?
