Static ethernet IP address
Posted: Thu, 2020-10-15 08:51
I am having trouble cofiguring the ethernet interface in the RB5 to have a static IP address for a point-to-point connection.
I started by adding the following two lines to /etc/dhcpcd.conf
That seemed to correctly change the ip address for eth0, but the computer at the other end of the ethernet link remained unreachable. After a lot of troubleshooting, I discovered that the eth0 interface was linked to a bridge on the RB5. Removing the bridge with the two following shell commands fixed the point to point connection.
ifconfig bridge0 down
brctl delbr bridge0
But every time the device reboots, bridge0 is configured and enabled again, so I have to re-enter those two commands every time.
Is there a way to permanently remove the bridge0 configuration? It suspect it is managed by QCMAP_ConnectionManager, but I have not found any documentation or examples that might illustrate how to do this.
Or is there a cleaner way to configure the ethernet interface with a static IP address while keeping the wifi interface configured via DHCP?
