I guess it is not much work to implement that (although we would need to add a API and GUI for that). 

>>But we already have ipsets, and there is DNS too. So I am not sure if we gain much.

We could create 1 ipset by alias, but I don't known if it's not too big memory overhead, as hashtable min size is 64.
But we can make ipset of ipset, it's a supported feature.

(For DNS, what do you have in mind? )


>> AFAIR I saw that feature on a CISCO firewall some time ago? 
Yes, indeed. (Currently it's the way I manage my cisco firewall ;)

I guess it is not much work to implement that (although we would need to add a API and GUI for that). 

But we already have ipsets, and there is DNS too. So I am not sure if we gain much. AFAIR I saw 
that feature on a CISCO firewall some time ago?
