LAN
The LAN configuration page is used to configure the LAN settings of the router 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.
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 refresh the Ethernet interface of your device or set an appropriate IP address range,
then enter the new IP address into your browser address bar to access the router.
DNS masquerading
DNS masquerading allows the router to proxy DNS requests from LAN clients to dynamically assigned DNS
servers. When enabled, clients on the router's LAN can then use the router as a DNS server without needing to
know the dynamically assigned cellular network DNS servers.
With DNS masquerading ON, the DHCP server embedded in the NTC-220 series router hands out its own IP
address (e.g. 192.168.1.1) as the DNS server address to LAN clients. The downstream clients then send DNS
requests to the NTC-220 series router which proxies them to the upstream DNS servers.
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 NTC-220 series router.
You may also override the DNS Masquerading option by specifying custom DNS Server IP addresses in the DHCP
Server configuration mentioned in the next section of this guide. In this case the DHCP server assigns downstream
devices the manually configured addresses and the DNS Masquerading option is ignored.
In most cases, it is not necessary to disable DNS masquerading but if you need to, click the DNS masquerading
toggle key to turn it OFF and then click the Save button. DHCP
The DHCP page is used to adjust the settings used by the router's built in DHCP Server which assigns IP addresses
to locally connected devices. To access the LAN configuration page, click on the Networking menu at the top of
the screen, click on the LAN menu on the left then select the DHCP menu item.
