5.2 Zones, Interfaces, and Physical Ports
Zones (groups of interfaces and VPN tunnels) simplify security settings. Here is an overview
of zones, interfaces, and physical ports in the ZyWALL.

5.2.1 Interface Types
There are many types of interfaces in the ZyWALL. In addition to being used in various
features, interfaces also describe the network that is directly connected to the ZyWALL.
features, interfaces also describe the network that is directly connected to the ZyWALL.
• Ethernet interfaces are the foundation for defining other interfaces and network policies.
You also configure RIP and OSPF in these interfaces.
• Port groups are created when you use the Interface > Port Roles screen to set multiple
physical ports to be part of the same (lan1, ext-wlan or dmz) interface. This creates a
hardware connection between the physical ports at the layer-2 (data link, MAC address)
level.

level.
• PPP interfaces support Point-to-Point Protocols (PPPoE or PPTP). ISP account settings
are included.
• Cellular interfaces are for 3G WAN connections via a connected 3G device.
• WLAN interfaces are for wireless LAN (IEEE 802.11b/g) connections via an installed
wireless LAN card.
• VLAN interfaces recognize tagged frames. The ZyWALL automatically adds or removes
the tags as needed. Each VLAN can only be associated with one Ethernet interface.

A zone is a group of interfaces and VPN tunnels. Use zones to apply security
settings such as firewall, IDP, remote management, anti-virus, and application
patrol. You can change the opt interface to be part of a different zone.

(Ethernet, VLAN,...)
Interfaces are logical entities that (layer-3) packets pass through. Use
interfaces in configuring VPN, zones, trunks, device HA, DDNS, policy routes,
static routes, HTTP redirect, and virtual server.
Port roles combine physical ports into interfaces called port groups.

The physical port is where you connect a cable. In configuration, you use
physical ports when configuring port roles. You use interfaces and zones in
configuring other features.
