we have just received a new internet connection. Our ISP have given us one DHCP address (which has been reserved for us) and another static IP address. I have configured the interface using the DHCP option which correctly receives all the required information and is working fine.
However, I don't seem to be able to add the second, fixed IP address. When I configure the interface as DHCP, the option to apply a secondary IP address is removed. Can I add one from the CLI?
