The web page bug for full wildcard FQDN support
Guru Member
So I just pinpointed the bug for this
Support FQDN wildcard for both root domain and subdomains on USG FLEX H — Zyxel Community
The issue is not the firmware (well maybe?) to support it but the web page not letting you.
So you can't do this
*grc.com because it say "Invalid wildcard FQDN address." you have to do *.grc.com but you can do *ionos.co.uk !
the issue is the number of dots!

Hi @PeterUK ,
Checked this against the current uOS firewall FQDN validation logic. It's actually working as designed, not a bug — only one wildcard and after removing the label containing the wildcard, the remaining domain part must have at least 2 sectors.
That's why:
*.grc.comand*ionos.co.ukare both accepted → remaining partgrc.comandyahoo.com= 2 sectors*.comand*grc.comare both rejected → remaining partcom= 1 sector

hi
I don't think that right Judy
because now *ionos.co.uk mean I can do
ionos.co.uk
www.ionos.co.uk
developer.hosting.ionos.co.uk
where as *.ionos.co.uk can only do
www.ionos.co.uk
developer.hosting.ionos.co.uk
Just like *.grc.com only the UI will not let me do *grc.com but will let me do *ionos.co.uk
