Out of the box, the Watchguard Firewall WebBlocker content filter does not permit Google Fonts to download and be viewed through the proxy and into your network. This creates a problem because a lot of websites now use embedded fonts to properly render the website.
To fix this, do the following:
- Log into the Watchguard Firewall
- Presuming you have already setup a Firewall proxy and are using the WebBlocker to filter content…
- Go to Firewall->Proxy Actions, and EDIT the current proxy you have custom defined.
- Go to HTTP RESPONSE->CONTENT TYPES
- ADD the following new actions (below). You will need to add ALL FIVE to make this work properly.

Hi. Has anyone got this to work. I do the above but the firewall still blocks the fonts.
So I recently spoke with a rep from watchguard and they had me do something different than what this proposes. They had me to go the “Firewall->Proxy Actions” and then edit the “HTTP-Client.QuickStart” and then go to “HTTP Response->Header Fields” and then at the bottom change the option that says “Action to take if no rule above is matched” from “Strip” to “Allow” and it fixed the problem.
