so standard disclaimer here: I am not an expert on this.

...but, it seems like setting up the proper subnet masks will be more
difficult if the 'normal' network (his existing) and the usb network
(ethernet gadget) for the neo are on the same 192.168.0.0/24 network.  I
know it can be subdivided beyond that by using different address masks. but
is this really handled natively with the standard iptables rules that one
finds via google, etc?

After changing usb and device IPs from their default for a while, I ran
into a conflict with an internal address range at work (when I connect over
VPN) and so moved my entire network to 10.x.x.x, which (thankfully) never
seems to get used for this stuff.

Am I totally wrong on this?
