10.13 Virtual Interfaces

Use virtual interfaces to tell the ZyWALL where to route packets. Virtual interfaces can also
be used in VPN gateways (see
page 557).
Virtual interfaces can be created on top of Ethernet interfaces, VLAN interfaces, or bridge
interfaces. Virtual VLAN interfaces recognize and use the same VLAN ID. Otherwise, there is
no difference between each type of virtual interface. Network policies (for example, firewall
rules) that apply to the underlying interface automatically apply to the virtual interface as well.

DESCRIPTION
Specify the IP addresses up to three DNS servers for the DHCP clients to use.
Use one of the following ways to specify these IP addresses.
Custom Defined - enter a static IP address.
From ISP - select the DNS server that another interface received from its DHCP
server.
ZyWALL - the DHCP clients use the IP address of this interface and the
ZyWALL works as a DNS relay.
Type the IP address of the WINS (Windows Internet Naming Service) server
that you want to send to the DHCP clients. The WINS server keeps a mapping
table of the computer names on your network and the IP addresses that they
are currently using.
Specify how long each computer can use the information (especially the IP
address) before it has to request the information again. Choices are:
infinite - select this if IP addresses never expire
days, hours, and minutes - select this to enter how long IP addresses are
valid.
Select this option to have the ZyWALL enforce links between specific IP
addresses and specific MAC addresses for this VLAN. This stops anyone else
from manually using a bound IP address on another device connected to this
interface. Use this to make use only the intended users get to use specific IP
addresses.
Select this option to have the ZyWALL generate a log if a device connected to
this VLAN attempts to use an IP address that is bound to another device's MAC
address.
Click this to configure static IP addresses for the ZyWALL to assign to
computers connected to this interface. See
Click WAN TRUNK to go to a screen where you can set this VLAN to be part of
a WAN trunk for load balancing.
Click Policy Route to go to the screen where you can manually configure a
policy route to associate traffic with this VLAN.
Click OK to save your changes back to the ZyWALL.
Click Cancel to exit this screen without saving.
