PIN Code Enter the PIN (Personal Identification Number) code (four to eight digits, 0000 for
example) provided by your ISP. If you enter the PIN code incorrectly, the cellular

ISP Access
Phone Number
Enter the phone number (dial string) used to dial up a connection to your service
provider's base station. Your ISP should provide the dial string.

string for CDMA-based networks.

automatically disconnects from the ISP.
WAN IP Address Assignment
Get automatically
from ISP
Select this option If your ISP did not assign you a fixed IP address. This is the
default selection and is the correct choice for most cellular ISPs, even when a
“static” IP is assigned to the 3G card.
Use Fixed IP
Address
Select this option If the ISP assigned a fixed IP address, subnet mask and default
gateway. This is not
commonly used by 3G cellular network operators, even when
a “static” IP is assigned to the 3G card.
My WAN IP
Address
Enter your WAN IP address in this field if you selected Use Fixed IP Address.
Advanced Setup
Enable NAT
(Network
Address
Translation)
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network (for example a private IP address used in a local
network) to a different IP address known within another network (for example a
public IP address used on the Internet).
Select this checkbox to enable NAT.
For more information about NAT see Chapter 13 on page 289.
Enable Multicast Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP is
a network-layer protocol used to establish membership in a Multicast group - it is
not used to carry user data.
Multicast Version Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast
Protocol) is a session-layer protocol used to establish membership in a Multicast
group – it is not used to carry user data. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
