airOS v5.5.4 User GuideThe following diagram shows the NanoStation at aresidence wirelessly connecting to a WISP tower.NanoStationWISP Tower• SOHO Router SOHO (Small Office/Home Office) Routermode is derived from Router mode. In SOHO Routermode, the main Ethernet port labeled functionsas the WAN port. The WLAN and other Ethernet portsfunction as the LAN. Each wireless or wired interface onthe WAN or LAN has an IP address.For example, SOHO Router mode is used in aninstallation where the main Ethernet port connects tothe Internet Service Provider (ISP) via a modem. Thefollowing diagram shows the airRouter HP wired to amodem, which is wired to the ISP.ISPChapter 5: Network TabDisable Network Disables the WLAN, LAN, or WANinterface(s). Use this setting with caution as you cannotestablish any Layer 2 or Layer 3 connection through thedisabled interface. You cannot access the device fromthe wireless or wired network that is connected to thedisabled interface.For more information about the Network Mode you havespecified, go to:• “Bridge” on page 27• “Router” on page 31• “SOHO Router” on page 40BridgeIn Bridge mode, the device forwards all networkmanagement and data packets from one networkinterface to the other without any intelligent routing. Forsimple applications, this provides an efficient and fullytransparent network solution.There is no network segmentation, and the broadcastdomain is the same. Bridge mode does not block anybroadcast or multicast traffic. You can configure additionalfirewall settings for Layer 2 packet filtering and accesscontrol.WLAN and LAN interfaces belong to the same networksegment and share the same IP address space. They formthe virtual bridge interface while acting as bridge ports.The device features IP settings for management purposes.Configuration ModeThe Network tab has two views, Simple and Advanced.Simple Basic configuration settings are available.Advanced configuration settings are hidden.Advanced Displays the advanced configuration settings:• Management Interface (in “Management NetworkSettings” on page 28)• “Interfaces” on page 29• “IP Aliases” on page 29• “VLAN Network” on page 29• “Bridge Network” on page 29• “Firewall” on page 30• “Static Routes” on page 30• “Traffic Shaping” on page 31Modem and airRouter HPUbiquiti Networks, Inc.27
