NethServer Version: 7.3.1611 (Final), Kernel release: 3.10.0-514.21.1.el7.x86_64
We had set up NethServer at office a few months ago. It is a physical computer (not a VM).
It runs in the following physical network configuration: Router > NethServer (RED - GREEN) > Network switch > Client computers
DHCP settings (GREEN)
Green zone: Transparent with SSL
No further configuration had been done, and everything was working fine since the past few months.
Then, last week, we decided to create a domain and installed AD.
Active Directory local accounts provider settings
DNS domain name: ad.myoffice.local
NetBIOS domain name: MYOFFICE
Domain Controller IP address: 10.10.0.2
The installation bridged the GREEN NIC, so we had to re-enable DHCP on br0 (the new GREEN). Apart from that, the installation was flawless and the domain, users, groups and shares are working as expected.
However, we now have a strange issue which was not present earlier. (Note that we always shut down the server every night, since the office power mains are switched off).
When the server starts, RED interface says “Link status is down” and none of the client computers can access the internet.
Simply editing and saving br0 (without any changes) via the Server Manager GUI, fixes this immediately.
I tried creating a script that runs “systemctl restart network” on boot. This fixes the internet access issue, however, the firewall blocks all non-HTTP traffic (FTP, Steam, etc.) until the above edit/save on br0 is performed.
I would appreciate if someone could:
- (URGENT) Please let me know what command to give in lieu of “systemctl restart network” so that the system performs the same restarts as when br0 is edit/saved via the Server Manager GUI.
- (Not critical if the above is achieved) Please let me know if there is some setting to be done, so that this issues goes away permanently.
Thanks a bunch!
