IP ADDRESSING
4.1
OVERVIEW
When Vanguard cellular router is connected to a cellular carrier, it will always have at least two IP addresses. The first is
the local area network (LAN) address. The Vanguard can be accessed through either the LAN 1 or LAN 2 Ethernet
connectors on the front panel using this IP address. This IP address is user configurable and is saved locally in the
Vanguard. The factory default IP address is 192.168.1.50 with a subnet mask of 255.255.255.0.
The second Vanguard IP address is assigned by the cellular carrier each time the Vanguard connects to the cellular
network. Often, this IP address is publicly accessible from the Internet, however in some instances the cellular carrier
may assign an IP address that is protected by firewalls. When a publicly accessible IP address is assigned, data flows can
be initiated from either the Vanguard or from the Internet. When an IP address is protected by cellular firewalls, data
flows can only be initiated from the Vanguard. In either case, after a data flow has been established, data is free to
move in both directions.
For mobile models equipped with Wi-Fi, the Vanguard will be assigned a third IP address on the Wi-Fi wireless network.

IP ADDRESSING TUTORIAL
The default LAN subnet of the Vanguard consists of addresses from 192.168.1.0 to 192.168.1.255. The first and last IP
addresses of a subnet are always reserved, no matter what the subnet size is. The first IP address in the subnet is the
Network ID. The last IP address in the subnet is the Broadcast Address.
The example below illustrates a sample Vanguard network. The subnet consists of IP addresses ranging from
192.168.1.0 to 192.168.1.255. The subnet mask is 255.255.255.0. This is sometimes written in shorthand notation as:
192.168.1.50/24 since the subnet mask 255.255.255.0 contains 24 ones then 8 zeros when it is converted to binary.
The first address 192.168.1.0 is reserved for the Network ID. The last address 192.168.1.255 is reserved for the
broadcast address. There are 254 valid IP addresses that may be assigned to hosts on the LAN network.
