hello everyone
Can i use FQDN on firewall rules. -
Like adding it here Firewall > Aliases > URLs and using the Alias created in a firewall rule ?
So yes.It would work well if the FQDN resolves to a single A or AAAA - even if this A or AAAA changes ones in a while (DYNDNS).

@Gertjan your are the best gertjan
thanks but how can i resolves to a single A or AAA

You don't need to.
I was mentioning "a single A or AAAA" because you can not use an alias like "facebook.com" which can resolve to hundreds of IP's.
A URL-Alias works fine for your site, my web site, the ones with a single IP.When you define an URL firewall alias, check out the resolver logs.
You'll l be seeing lines like :
Looking a bit closer and you see a task runs every 5 minutes or so to re resolve all the URL you use. If one changes, the firewall rules are reload.
