Raven X EV-DO for Verizon - User Guide, version 2.34 25
Data Communication and Host Modes
Public and Private Mode
By default, the Raven X is in Public Mode and will pass the IP address assigned by the Verizon
network to the devices connected to its ports. If you need more control over which gateway
address, device address, and netmask that is given out by the DHCP server, you can use the pri
-
vate host mode, *HOSTPRIVMODE, and set the internal network IP addresses. The Raven X
will use NAT to forward packets to the end device.
Note: When using Public mode, connect the modem directly to the computer or
other end device. Using a hub or switch may prevent the modem from updating
the IP address of the end device when an IP address is received from the Verizon
network.
In Wireless Ace, the Private mode settings are part of the PPP/Ethernet group.
FIGURE 7. Wireless Ace: Private Host Mode
• *HOSTPRIVMODE - Set to 1 to enable the explicit IP addresses.
• *HOSTPRIVIP - Set to the IP address you want the Raven X to give to your device.
• *HOSTPEERIP - Set to the IP address you want for the Raven X.
• *HOSTNETMASK - Set to the subnetmask (generally, 255.255.255.0).
Note: If you are using Private Mode (*HOSTPRIVMODE=1), you will need to
make sure that *HOSTPRIVIP and *HOSTPEERIP are on the same subnet. If the
subnet mask is 255.255.255.0, it is safe to use 192.168.x.y for each as long as the x
is the same number (0 in the example screen shot above) and the y is different (1
and 2 in the example) and between 0 and 254. The screenshot shows an example.
Internal DHCP Server
DHCP (Dynamic Host Configuration Protocol) has become a primary component of today’s net-
work environments. DHCP allows one server to automatically and dynamically allocate network
IP addresses and other network related settings (such as subnet masks, routers, etc.) to each com
-
puter or device without the need to set up each specifically or keep track of what addresses have
already been used.
