If the third-party router’s WAN interface is attached to the Digi device’s Ethernet port, and
the Digi device’s mobile interface receives the IP address 166.213.2.215, the router’s
WAN port is assigned the same IP address 166.213.2.215. If the router is receiving the IP
address dynamically; the DNS server addresses, subnet mask, and default gateway
information will be filled in automatically. If the router is configured manually; you need
to obtain the DNS information from the mobile service provider and enter that manually.
The subnet mask is 255.255.255.0 and the default gateway is the same as the mobile IP
address with “.1” for the last octet. In other words: if the mobile IP address is
166.213.2.215, the default gateway is 166.213.2.1.
