        Yes it should. I deliberately typo'd it to show what happens.
        It sees it as an FQDN as it's not a valid IP address and tries to resolve it. And of course that fails resulting in the errors shown.

          yeah, deleted my post as I overlooked the mention of 'not a valid IP address' in your original

            Thanks for your support and suggestions.
            I have no filterdns entries in the logs until now.
            I will keep an eye on it.

            Remember that the same configuration on 2.4.3_p1 gives me no issues.

              The most likely thing there is you're hitting something really obscure that passes in php 5.6 but not in php 7. I would have expected some error though but it may simply interpret it differently.

                Hi to all,
                I have an update: facing the same problem on 2.4.4_p1
                I have an alias like
                FQDN_Hamal
                corrisponding to
                hamal.intranet

                The name is correctly resolved like
                *drill hamal.intranet @127.0.0.1
                ;; ->>HEADER<<- opcode: QUERY, rcode: NOERROR, id: 9055
                ;; flags: qr rd ra ; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0
                ;; QUESTION SECTION:
                ;; hamal.intranet.dynameeting.it. IN A

                ;; ANSWER SECTION:
                hamal.intranet 16 IN A 192.168.212.135

                ;; AUTHORITY SECTION:

                ;; ADDITIONAL SECTION:

                ;; Query time: 0 msec
                ;; SERVER: 127.0.0.1
                ;; WHEN: Thu Dec 27 11:36:32 2018
                ;; MSG SIZE rcvd: 63*

                The corresponding table was empty, so the corresponding permit rule was never triggered (trafic dropped)

                I tried adding via command line
                pfctl -t FQDN_Hamal -T add hamal.intranet
                it sometimes works giving
                1/1 addresses added
                sometimes does'nt work
                0/1 addresses added
                The corresponding log in filterdns is allways
                filterdns: Adding Action: pf table: FQDN_Hamal host: hamal.intranet

                I have no idea why this happens.
                Can anyone help me?

                  First, you wouldn't inject an alias entry using pfctl that way for a hostname. The filterdns daemon manages that internally.

                  Second, if it works sometimes and not others, it could be either because the host can't be resolved, or that it's already in the table.

                  The adding action log entry means filterdns read that entry from the config, not that it successfully resolved the host.

                    Hi Jimp,
                    I know I should not add hostnames like this, I'm simply trying to make the problem clearer.
                    The table itself should hold only one entry (resolved to 192.168.212.135)
                    If I try to inject a non valid fqdn I get an error:
                    pfctl -t FQDN_Hamal -T add hamal2.intranet
                    no IP address found for hamal2.intranet

                      So this is an internal domain, how are your DNS on pfSense configured. Make sure pfSense only uses name servers that can resolve those internal domains.

                        Hi Grimson,
                        sorry for the delay (and Happy New Year to all).
                        The DNS is configured to point
                        2 internal DNS server (reachables)
                        2 external DNS servers (google)

                        I 've just removed the google ones and I will let you know

                        Regards.

                          Hi,
                          Today the problem is back again: some table are void: non traffic allowed despite the dns pointing only internal servers.

                            And still no filterdns errors on the resolver log? Or system log?

                              No errors in system log.
                              No relevant errors in resolver log (only a few failed to resolve host : new_name.internal , due to devices that are already configured on the firewall but not on the dns server. Those entries have no concern with the void tables.)

                              Regards
