Feedback on Firewall — Aliases

Feedback: While the documentation does clearly state that hostname aliases only look up A and AAAA records, it might be helpful to specifically point out that CNAME records aren't resolved. I use DNS aliases only to block IPv6 to a few services who's IPv6 implementation often hiccups, but this is a critical nuance to note if someone were to use them for security reasons.

It resolves CNAME records OK when I try it. You may have some other issue in your DNS setup. This site is not for support or diagnostic discussion.
For assistance in solving problems, please post on the Netgate Forum .

In that case the documentation should mention that it does follow CNAME.

It's a natural part of DNS that CNAMES would be followed by a resolver. So long as the end result is an A/AAAA record. I don't see the need to call it out specifically.
