I have multiple VLANs configured on my VE host and manged and routed in my router/firewall, the thought just crossed my mind if I needed to add inter vlan firewall rules to block traffic on the host itself. The simple question being how does internal routing/switching happen on the host? Is it possible for two vlans on different vlans or subnets to comunicate on the host without going through my router/firewall? Most notably I want to make sure my DMZ traffic can't bleed over.
