Danb35 is quite correct in this sense. The Nethserver DNS (unbound?) works well enough for SOHO environments who don’t need more.
If the environment contains a mailserver (Not the Nethserver) or even worse, more than one mailserver there is NO possibility to add in MX Records. You can’t even add in an Alias. The “Alias” in Nethserver is ONLY for Server aliases.
If I manually add in an alias, example:
myserver.domain.tld = 192.168.20.30
is the server’s FQDN (Not the NethServer!)
and I’d like that server to be reachable with
myalias.domain.tld, then the only option I have is to make a second entry like
myalias.domain.tld = 192.168.20.30
Now, this works, BUT:
The reverse DNS (PTR) now points 192.168.20.30 to myalias.domain.tld instead of the correct myserver.domain.tld.
Also no UI for adding in TXT, SVC or other stuff besides using a custom template.
I love NethServer, but there should be an Option to choose a simple repeater like Unbound-DNS or a full blown BIND or some other DNS.
Sure, there are a few stuff which is VERY simple in Unbound:
Say blocking access to Facebook or whatever:
Make an entry like *.facebook.com = 127.0.0.1 - that simple!
Two years back, one of my clients had the only working UPC Internet Cable connection, as none of the other clients had an internal DNS (mine did, a full BIND without any need for provider DNS…). The complete DNS Services of UPC in Switzerland was down, but the Network was working…
My 2 cents
