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-2172 antenna.
With DNS masquerading ON, the DHCP server embedded in the CFW-2172 antenna hands out its own IP address
(e.g. 192.168.0.1) as the DNS server address to LAN clients. The downstream clients then send DNS requests to the
CFW-2172 antenna which proxies them to the upstream DNS servers.
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.
The DNS masquerading toggle key is OFF by default.
