DNS Domain name: local.durerocaribe.cu
NetBIOS domain name: DUREROCARIBE

This NS7.5 instance is a Proxmox 5.2 KVM and is using a proxy [Network] -> [Proxy settings]. Seen the update of the server worked

yum update

I assumed that the server had Internet access, however server journal is giving this:

# journalctl -x | grep -i 'error downloading' -A 100 -B 100

So I’m thinking is a proxy related issue

Whats the server name? Something like server.local.durerocaribe.cu?

Do you have a br0 interface and did you set it up for KVM?

http://docs.nethserver.org/en/v7/accounts.html#kvm

Does it work without proxy?

Do you use IPS?

Server FQDN is odin.durerocaribe.cu

Yes, Proxmox 5.2 has a bridge named vmbr0 and I it’s set it to promiscuous mode:

# ifconfig vmbr0

        inet ###.###.###.###  netmask ###.###.###.###  broadcast ###.###.###.###

I can’t tell, HTTP/HTTPS network traffic most go trough proxy, country enforced policies, however, I think this is not the problem as I’m able to update the system. It might be a problem related to something else.

Yes

Problem solved !!! Bad firewall rule setting, I definitely need a how-to for nethserver firewall rule setting, thanks @mrmarkuz

BTW, I have I few questions:
What’s the difference between a [service object] and a [network service] ?
The rule:
REJECT [green] -> [firewall]
implies that any routing request coming from an green interface IP is gonna be rejected ?

7

Both describe some port definitions.
A network service is an installed Nethserver service with it’s defined ports and a service object is a protocol like HTTP with it’s defined ports. The service objects are editable firewall objects. The network services are the installed services.
For example, you can open all ports for the network service dovecot which will open IMAP(S), POP3(S), sieve etc. or you just open the port for service object IMAPS.

It rejects any packet that goes from green zone to the firewall. Routing from green to red should still work. The Nethserver services like DNS could not be reached from green anymore.

So when one uses [firewall] either as source or destination, it implies that requests to or responses from the server, which is acting as a firewall, should be rejected, Am I right?

Yes, you’re right.
