LAN configuration
The LAN configuration page is used to configure the LAN settings of the antenna and to enable or disable
DNS Masquerading. To access the LAN configuration page, click on the Networking menu at the top of the
screen, then click on the LAN menu on the left.
Figure 42 – LAN configuration settings
The default IP of the LAN port is 192.168.1.1 with subnet mask 255.255.255.0.
To change the IP address or Subnet mask, enter the new IP Address and/or Subnet mask and click the
Save button.
Note – If you change the IP address, remember to reboot the antenna and enter the new IP address into your browser address bar.
DNS masquerading
DNS masquerading allows the antenna to proxy DNS requests from LAN clients to dynamically assigned
DNS servers. When enabled, clients on the antenna’s LAN can then use the antenna as a DNS server without
needing to know the dynamically assigned cellular network DNS servers.
The DNS masquerading toggle key is OFF by default.
With DNS masquerading OFF, the DHCP server hands out the upstream DNS server IP addresses to
downstream clients directly, so that downstream clients send DNS requests directly to the upstream DNS
servers without being proxied by the CFW-2182 antenna.
