Can't access virtual interface eth0:0



Hi guys, :face_with_raised_eyebrow:

I’m trying to setup a service that starts a TFTP server but it needs to run on a specific IP address let’s say:
For that I created a virtual interface eth0:0 like this:
ifconfig eth0:0 netmask

My pi3 is connected to a switch that allows me to bridge the 10.0.1.* network between devices yet I can’t download or upload files to this address, this address is simply not visible from outside the container.

Why would eth0 be fully reachable but not eth0:0 ? :thinking:
