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.

Physical Ports

(WAN, LAN, DMZ)

(Ethernet, VLAN,...)

Physical Ethernet

(P1, P2,...)

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.

• Ethernet interfaces are the foundation for defining other interfaces and network policies.

You also configure RIP and OSPF in these interfaces.

• Port groups create a hardware connection between physical ports at the layer-2 (data link,

MAC address) level.

• PPPoE/PPTP interfaces support Point-to-Point Protocols (PPP). ISP accounts are

required for PPPoE/PPTP interfaces.

• 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.

• Bridge interfaces create a software connection between Ethernet or VLAN interfaces at

the layer-2 (data link, MAC address) level. Then, you can configure the IP address and

subnet mask of the bridge. It is also possible to configure zone-level security between the

member interfaces in the bridge.

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

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 groups combine physical ports into interfaces.

The physical port is where you connect a cable. In configuration, you use

physical ports when configuring port groups. You use interfaces and zones in

configuring other features.
