We have a radius server which allows our employees to connect to the internet via 3G modems running through a microwave link at our offices. The problem is that they can access any website (social, mature content etc). We have a local Barracuda web filter for our network in the offices which filters websites in order to prevent abuse. Please keep in mind that this network has another internet connection. The office network's gateway is the web filter's IP and microwave network has it's own gateway.
Microwave gateway is 192.168.X.12
Barracuda web filter is 192.168.X.5
Is there a way we can configure radius server traffic through our local web filter?
