• Between the router and VLAN 3.
VLAN Interfaces Overview
In the ZyWALL, each VLAN is called a VLAN interface. As a router, the ZyWALL
routes traffic between VLAN interfaces, but it does not route traffic within a VLAN
interface. All traffic for each VLAN interface can go through only one Ethernet
interface, though each Ethernet interface can have one or more VLAN interfaces.
Note: Each VLAN interface is created on top of only one Ethernet interface.
Otherwise, VLAN interfaces are similar to other interfaces in many ways. They
have an IP address, subnet mask, and gateway used to make routing decisions.
They restrict bandwidth and packet size. They can provide DHCP services, and
they can verify the gateway is available.
