The device can act as a DHCP server and use Network Address Translation (Masquerading), which is widely used by APs. NAT acts as the firewall between the LAN and WAN. • For example, Router mode is used in a typical Customer Premises Equipment (CPE) installation. The device acts as the demarcation (demarc) point between the CPE and Wireless Internet Service Provider (WISP), with the wireless interface of the device connecting to the WISP. The following diagram shows the NanoBeam at a residence wirelessly connecting to a WISP tower. NanoBeam WISP Tower SOHO Router Mode The device operates in Layer 3 to perform routing and enable network segmentation – wireless clients and the WAN interface are on a different IP subnet. SOHO Router mode blocks broadcasts and can pass through multicast packet traffic. You can configure additional firewall settings for Layer 3 packet filtering and access control. The device can act as a DHCP server and use Network Address Translation (Masquerading), which is widely used by APs. NAT acts as the firewall between the LAN and WAN. • For example, SOHO Router mode is used in an installation where the main Ethernet port connects to the Internet Service Provider (ISP) via a modem. In devices with one Ethernet port (while operating in Access Point or AP‑Repeater mode), SOHO Router mode works like Router mode, except that the LAN port works as a WAN port, and the WLAN works as the local network. In devices with two or more Ethernet ports, the main Ethernet port becomes the WAN port, and the WLAN and other LAN ports become the local network. Note: Do not use the SOHO Router mode in combination with Station wireless mode; this may cause the device to become inaccessible. If this did happen, reset the device to defaults; press and hold the Reset button for eight seconds and then release it. Disable Network Disables the WLAN, LAN0, or LAN1 interface(s). Use this setting with caution as you cannot establish any Layer 2 or Layer 3 connection through the disabled interface. You cannot access the device from the wireless or wired network that is connected to the disabled interface. Configuration Mode The Network page has two views, Simple and Advanced .
