    using v23 and find that under Access Restrictions, help mentions the ability to pick policy type. That is, to filter outbound connections or inbound connection to router. I want to allow only specific IP addresses to be able to get through the router on port forwarding that is already set up. However, I do not see a radio button that will allow me to filter Inbound Traffic. I really want to do this. Is version 23 capable of allowing for Inbound filtering?

    You can do it with iptables. Can you give more information on what protocol, port and destination ip you are working with?

    I would like to know how to configure iptables to only allow certain IP addresses to access a port on my one of my PCs. I currently use the "Port Range Forward" option to allow access to port 54000 over TCP to the local address of I would love to be able to limit access to that port to specific addresses.
