http://serverfault.com – I can't find answer about how linux processes incoming packets from different VLANs, that do not belong to a subnet assigned to a VLAN. Imagine this situation. On Linux machine with the following configuration: eth0.100 - assigned address from 192.168.100.0/24 subnet (eg. 192.168.100.2) eth0.150 - assigned address from 192.168.150.0/24 subnet (eg. 192.168.150.2) eth0.200 - assigned address from 192.168.200.0/24 subnet (eg. 192.168.200.2) the address of the default gateway is 192.168.100.1 pointing to interface eth0.100 On port eth0.150 comes packet with a source address 10.0.0.100/24 address (HowTos)
