Hello there,
I'm using an ethernet connection that gives access based on the MAC address of clients.
The connection works, but using NetworkManager it fails at the DHCP lease renewal step after some time and I get stuck with an old IP address that I cannot use, I tried both the integrated dchp client and dhclient.
Using systemd-networkd works fine and the renewal goes well.
Do you know what could be the problem? What dhcp client does systemd use?
@galeot That wouldn't work, I need a fixed mac address or the gateway will reject my connection since it accepts clients based on the mac address.
