Only IPs work for Firewall Alias "Host(s)", not able to use a FQDN

[dgk]

I am allowing along certain hosts to a firewall rule.

If I try to use a FQDN in the "content" field of a FW alias Host(s) then use that alias the firewall does not allow that host as a source. 

But if I replace in that "content" field of the alias with the actual IP of the that host then the firewall works correctly allowing access to that alias. 

If I use the opnsense DNS lookup under interfaces/diagnostics that FQDN is properly looked up. 

So what am I missing here.  Why can't I use FQDN with an alias pointer.

What FQDN are you using?  Host.Domain works for me in the Hosts aliases.

Try to inspect the alias via Firewall>Diagnostics>Aliases and see if it gets resolved properly.
