Hello I have a server setup with the following network config: Default eth0 - 192.168.100.1 255.255.255.0 GW:192.168.100.254 VLAN2 eth0.2 - 0.0.0.2 255.255.255.255 VLAN3 eth0.3 - 0.0.0.3 255.255.255.255 VLAN4 eth0.4 - 0.0.0.4 255.255.255.255 The reason for this is that I run VMWare server and the other VLANS are used by the VMWare server.. Without setting any IP, I got errors.. I have a VLAN truck from my HP-managed switch. All VLANS tagged except Default VLAN (I have tried this with tagging on Default VLAN also). If I add my linux desktop to VLAN4 and do a netdiscover, it will find the 192.168.100.1 (I can not access it, but since it is detectable from outside, it is a risk). I do not have the VMWare running when doing this, so that does not interfere. Why do netdiscover see the interface? I also tried moving the 192.168.100.1 interface to another physical interface, but netdiscover still reports it.
