Chapter 6 Configuration Basics 6.3 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 ISG50. Figure 66 Zones, Interfaces, and Physical Ethernet Ports Zones Interfaces WAN wan1 wan2 LAN1 LAN2 DMZ lan1 lan2 dmz Physical Ports Table 13 Zones, Interfaces, and Physical Ethernet Ports Zones A zone is a group of interfaces and VPN tunnels. Use zones to apply security settings (WAN,LAN, DMZ) such as firewall, and remote management. Interfaces (Ethernet, VLAN,...) Interfaces are logical entities that (layer-3) packets pass through. Use interfaces in configuring VPN, zones, trunks, DDNS, policy routes, static routes, HTTP redirect, and NAT. Physical Ethernet Ports (P1, P2, ...) Port roles 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. 6.3.1 Interface Types There are many types of interfaces in the ISG50. In addition to being used in various features, interfaces also describe the network that is directly connected to the ISG50. • 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. Port groups are created when you use the Interface > Port Roles screen to set multiple physical ports to be part of the same (lan1, lan2 or dmz) interface. • PPP interfaces support Point-to-Point Protocols (PPPoE or PPTP). ISP accounts are required for PPPoE/PPTP interfaces. • VLAN interfaces recognize tagged frames. The ISG50 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. 92 ISG50 User's Guide
