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. > For now I set the native VLAN to VLAN 1 and that works. 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.
