A young and pretty Linux server OS that takes a bit of work Zentyal 2 is something a little bit different, although it too has changed its name recently: version 1 was called e-Box. A decade younger than its rivals, it is based on Ubuntu, but its developers skip the normal semi-annual releases, and only use the Long Term Support ones that Canonical releases every other year. E-Box …
in a straightforward way, if you need to change the defaults. Pasted from the relevant page:-

Filtering rules from internal networks to Zentyal
These rules allow you to control access from internal networks to services running on your Zentyal machine.
Filtering rules for internal networks
These rules allow you to control access from internal networks to the Internet and traffic between internal networks. If you wish to provide access to your Zentyal services, you must use the above section.
Filtering rules for traffic coming out from Zentyal
These rules allow you to control access from your Zentyal to external services.
Filtering rules from external networks to Zentyal
These rules allow you to control access from external networks to sevices running on your Zentyal machine.
Be advised that adding rules in this section may compromise your network security as you may grant access from untrusted networks. Please do not use this unless you know what you are doing.

Rules added by Zentyal services (Advanced)
These rules are automatically added by the Zentyal services.
You can disable these rules, but make sure you know what you are doing or otherwise some services could stop working. "
while you can install zentyal as an all in one it's designed to be modular so you install it across as many servers as you want.
Even if you don't want to separate everything out to different servers it's pretty easy to use the firewall to select what's available on any particular interface.
I have friends that are big fans of the all-in-one (gateway and server) concept - I'm more of the modular approach (even if I run both on the same machine I'd want to VM the two roles in separate instances) but it's good to know, with Zentyal at least, it's straight forward to deploy an all in one config and control what's available on one side vs. the other.
Cheers!
Thanks for taking the time to test all kinds of new Linux server distros.
Whenever I'm at the 12-month distance from a LTS update of Ubuntu I'm unsure what to install, and custom servers such as this one offer an alternative. Since they're based on Ubuntu server they also offer a degree of familiarity which is a definite bonus.
Also, what is an un-necessary feature for one admin is invaluable for another: the lan-only webmail if it also allows for lan-only e-mail would be a much sough-after feature for myself. I'm also interested in the bandwidth shaping at the gateway aspect of th is server, especially if it's relatively simple to set up.
