Finally had the opportunity to get back to this.
Having internet connection restored, everything seems to be working as supposed
to. One simple query from my client and one response from my server.
Output from wireshark:

Just 2 packets.
great, it works.
But on the command line I get the following, and I'm confused why the
"non-authoritive answer":
Non-authoritative answer: -----------------------here!???
8.66.136.193.in-addr.arpa canonical name = 8.0-28.66.136.193.in-addr.arpa
this happens your server is not authoritative for the
66.136.193.in-addr.arpa domain.
I guess your servers don't fetch 66.136.193.in-addr.arpa from your ISP.
I also wasn't able to reach your servers:
8.66.136.193.in-addr.arpa. 86400 IN CNAME 8.0-28.66.136.193.in-addr.arpa.
0-28.66.136.193.in-addr.arpa. 86400 IN NS dns2.di.ubi.pt.
0-28.66.136.193.in-addr.arpa. 86400 IN NS dns.di.ubi.pt.
;; Received 121 bytes from 193.136.2.228#53(ns02.fccn.pt) in 56 ms
% dig -x 193.136.66.8 @dns.di.ubi.pt.
dig: couldn't get address for 'dns.di.ubi.pt.': failure
% dig -x 193.136.66.8 @dns2.di.ubi.pt.
dig: couldn't get address for 'dns2.di.ubi.pt.': failure
so there's another problem to solve.
IN NS dns.di.ubi.pt.
IN NS dns2.di.ubi.pt.
looks like your servers dns.di.ubi.pt (193.136.66.1) and dns2.di.ubi.pt
(193.136.66.2) aren't reachable from internet.
