There is no need to create virtual interfaces like eth0:1 to be able to have secondary IP addresses. The ip command adds them to the same eth0 interface. When I use VPN I can see that my interface has a secondary LAN address created by VPN, but it does not have an additional virtual NIC. The only thing is that if my primary IP address goes down temporarily, the secondary address becomes primary and stays there. I need to look at the VPN configuration to see how to define the VPN LAN as a secondary subnet, but this is not related to your question. PS. Did you look at setting your desired subnet rather than a local-link auto-configured address at your HDHomerun device? -- Regards, Mick
