NethServer Version: 7.9.2009
I previously installed Nethserver with a dummy LAN interface and I have now installed a second physical LAN interface.
I would like to know how to remove the dummy interface and configure the new physical LAN interface instead. Can this be solved without data loss or need to be reinstalled?
Thank you for your help.
This could be solved. But maybe it’s better if you tell us a bit more about your setup 
What information should I give you?

Thank you for your help.
I think you just need to add the new real interface to bridge br0 and remove the dummy interface from the bridge.
Always good to have a backup, in case something goes wrong.

Thank you for your answer. I will look into it shortly, but unfortunately I got stuck with another problem.
I want to put Nethserver on a separate subnet behind my router but unfortunately there is a problem setting it up. I have to fix this first, otherwise I won’t be able to access Nethserver.
Thanks and Regards
If the network of the dummy interface is not the same as the new one you need to change the IP of the samba AD container.
On Neth command line you may use the network-recovery tool to quickly set an IP address to access Nethserver again.

Thank you for your advice. The br0 bridge and dummy interface network was the same as the samba AD network so the solution was simple.
I studied the network reconfiguration in the GUI and managed to solve it. It is important to first add the physical interface to the br0 bridge, and after this is done, remove the dummy interface from the br0 bridge by reconfiguring the network in a separate step. The Nethserver is then available from the new green interface and everything works.
Thanks and Regards
