So just came over from Zentyal and thought I will give nethserver a go. But running into a few basic issues which are a bit uncomfortable.
Specifying port ranges in a firewall rule is common an basic and I have been unable to get this right. Please do not point me at the other article where the gentleman used the creation of a service to work around the problem, as creating a network service in 6.7 seems to be problematic as well. (see my previous problem) no longer an option to specify private or public access (or I do not know where that can now be specified) which will force the network service.
I am not going to type 50 ports with commas in-between, (and that for many rule entries) so please help me or I will be forced to move back to zentyal and I would really like to try NethServer.
