    I've been tasked with controlling access to our internet connection and it looks like the best way to do this is with a proxy server. I'm hoping there is a way to forward all outbound port 80 and 443 traffic to a specific IP address (the IP of my proxy server); sort of like reverse port forwarding. We have an RV082 with the latest firmware applied (1.3.5). Is there a way to do this?

    Yes, I can force all users to use the proxy server with a GPO, but we're more concerned with rougue PCs being connected to our LAN. Right now, if someone brings in a laptop and plugs it into a LAN port, they have virtually unfiltered and uncontrolled access to the internet. If I can force all port 80 and 443 traffic at the router level to go through our proxy server we could lock this down.

    Any thoughts/suggestions? Maybe something with static routes?

    Forwarding will not work, but you can prevent the eventual notebook user from using it directly.

    For that create 2 firewall rules: one allows the proxy server to connect to port 80 of any host on the internet. The next one deny access to port 80 to everyone. This way only the proxy will be able to connect to port 80 outside.
    Repeat for port 443.
