Chapter 10 Interfaces 10.5.3 Virtual Interfaces Use virtual interfaces to tell the Zyxel Device where to route packets. Virtual interfaces can also be used in VPN gateways (see Chapter 30 on page 605) and VRRP groups (see Chapter 42 on page 778). 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, security policies) that apply to the underlying interface automatically apply to the virtual interface as well. Like other interfaces, virtual interfaces have an IP address, subnet mask, and gateway used to make routing decisions. However, you have to manually specify the IP address and subnet mask; virtual interfaces cannot be DHCP clients. The virtual interface uses the same MTU and bandwidth settings that the underlying interface uses. Unlike other interfaces, virtual interfaces do not provide DHCP services, and they do not verify that the gateway is available. This screen lets you configure IP address assignment and interface parameters for virtual interfaces. To access this screen, click the Create Virtual Interface icon in the Ethernet, VLAN, or bridge interface summary screen. Figure 249 Configuration > Network > Interface > Create Virtual Interface Each field is described in the table below. Table 108 Configuration > Network > Interface > Create Virtual Interface LABEL DESCRIPTION Interface Properties Interface Name This field is read-only. It displays the name of the virtual interface, which is automatically derived from the underlying Ethernet interface, VLAN interface, or bridge interface. Description Enter a description of this interface. It is not used elsewhere. You can use alphanumeric and characters, and it can be up to 60 characters long. IP Address Assignment IP Address Enter the IP address for this interface. Subnet Mask Enter the subnet mask of this interface in dot decimal notation. The subnet mask indicates what part of the IP address is the same for all computers in the network. ZyWALL USG Series User's Guide 327

Virtual Interfaces

Use virtual interfaces to tell the Zyxel Device where to route packets. Virtual interfaces can also be used

in VPN gateways (see

Chapter 30 on page 605

) and VRRP groups (see

Chapter 42 on page 778

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, security policies) that apply to the

underlying interface automatically apply to the virtual interface as well.

Like other interfaces, virtual interfaces have an IP address, subnet mask, and gateway used to make

routing decisions. However, you have to manually specify the IP address and subnet mask; virtual

interfaces cannot be DHCP clients. The virtual interface uses the same MTU and bandwidth settings that

the underlying interface uses. Unlike other interfaces, virtual interfaces do not provide DHCP services,

and they do not verify that the gateway is available.

This screen lets you configure IP address assignment and interface parameters for virtual interfaces.

DESCRIPTION

Interface Properties

Interface Name

This field is read-only. It displays the name of the virtual interface, which is automatically

derived from the underlying Ethernet interface, VLAN interface, or bridge interface.

Description

Enter a description of this interface. It is not used elsewhere. You can use alphanumeric and

()+/:=?!*#@$_%-

characters, and it can be up to 60 characters long.

IP Address

Assignment

IP Address

Enter the IP address for this interface.

Subnet Mask

Enter the subnet mask of this interface in dot decimal notation. The subnet mask indicates

what part of the IP address is the same for all computers in the network.
