Our Web Filter 410 is inline on our local area network. A wireless client basically connects to wifi > switch > web filter > link balancer/router > internet.
I'm working to filter Chromebooks which don't have the luxury of the WSA (web security agent). They are filtered inline when on location... it's off location I'm trying to accomplish. I have configured the proxy for remote clients as illustrated here: https://techlib.barr...tingsChromebook Great! This works for remote clients. (required a simple port forwarding added to router, but simple stuff)
The issue I'm having is when a proxied device comes back to our local area network when the proxy setting is added. This device will not resolve. I suspect because it's going wifi > switch > web filter > router > internet > back to web filter via proxy > internet. Something's getting jacked here.
Is anyone using Chromebooks and successfully filtered them both on and off site? Any tips? I can remove the proxy setting and things work again on site. However, if I enable the ability to change the proxy setting, it can and will be defeated at home. And, who wants to change this every day?
Barracuda Link Balancer 330 is handling the port forwarding
Barracuda Web Filter 410 is our web filter
I'm using the default port 3128 and our static/public IP. I can see traffic from a home machine going through the web filter as the IP from the ISP shows in the web filter's web log. So, this is configured according to documentation and functions perfect for remote machines... just not when a device with this configuration comes back on our network.
