That's not a mistake, per se. Having vlan 48 as the native vlan just
means that you'd want 192.168.48.100 on eth0 instead of eth0.48.

As long as you aren't concerned about the security implications of that
host having access to vlan 1, that seems pretty reasonable. The system
will get some extra broadcast traffic, but the ethernet card will
probably filter those out so that they don't have to be processed.
