Q: re URL filter 2.29 CU 201

Is there any point in having URL filter enabled in Web Proxy page, especially now DNS filtering implemented?

Have checked a few of my firewalls and nothing logged in URL filter logs for last month.

Guessing as most web sites now https and URL filter default settings filter http only.

Similarly, in URL Filter configuration page, should download source be IPFire DBL rather than Univ. Toulouse?

Probably not. At least if you are using URL Filter only for blocking. That is by far the most popular feature.

The remaining features of URL Filter are probably not very relevant any more, so I would strongly suggest to move forwards the DNS Firewall and replace URL Filter.
