III supports 3G dialup connection type to access Internet. Please contact your Internet Service
Provider before configuring the required parameters.
3.1.1.1 3G Settings
This section is where you configure your dialup up connection type. There are 2 modem types to
choose from: Cellular 2G and 3G.
2G/3G ISP Settings: Your 2G/3G service provider will provide you with the values to fill in for
the required fields of Access Point Name (APN Gateway),PPP User Name, PPP Password
and Dial Number.
PIN: In case your SIM card has the PIN code setup, you must input the correct pin code for the
authentication of the dialup. Wrong input of Pin Code will make SIM card locked.
Dial Number: The 2G/3G dial command. Default is *99#.
Authentication Mode: The mode for PPP authentication.

3.1.2 LAN
These are the settings of the LAN (Local Area Network) interface for the router. The router's local
network (LAN) settings are configured based on the IP Address and Subnet Mask assigned in this
section. The IP address is also used to access this web-based management interface. It is
recommended that you use the default settings if you do not have an existing network.
IP Address: The IP address of your router’s LAN port. Default: 192.168.0.254.
Subnet Mask: Subnet Mask of your LAN (default: 255.255.255.0). All devices on the network
must have the same subnet mask to communicate on the network.
DHCP Type: DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is
where you configure the built-in DHCP Server to assign IP addresses to the computers and
other devices on your local area network (LAN). When you select Server item from this
pull-down list to enable this function, the following parameters will be displayed. You must enter
the IP address, Subnet Mask, Primary DNS Server and/or Secondary DNS Server.

SM3G IIIUser’s Manual

Start IP Address: Specify the DHCP Client IP address that will start.
End IP Address: Specify the DHCP Client IP address that will end.
Note: The number of the “End IP” must be greater than “Start IP”, and cannot be the same as the
router’s IP address.
DHCP Lease Time: Designate the amount of the time for the device to recycle and give out
the IP addresses to the devices in your network (default: 86400).
Statically Assigned: You can statically assign the client MAC and IP address. Up to three
IPs and MACs can be assigned.

SM3G IIIUser’s Manual

3.1.3 DHCP Clients
In this section, you can see clearly which devices are currently leasing IP addresses that you had
defined for the DHCP Server‘s allocation of addresses to computers and devices on your Local Area
Network.
Host Name: A name for each computer or device that is given an IP address by the DHCP
Server. This may help you keep track of which computers are assigned this way.
MAC Address: A MAC address is usually located on a sticker at the bottom of a network
device. The MAC address is comprised of twelve digits. Each pair of hexadecimal digits are
usually separated by dashes or colons such as 00-0D-88-11-22-33 or 00:0D:88:11:22:33.
IP Address: The address which is obtained from the DHCP Server.
Expires in: The remaining time of the IP address’s lease. A specific LAN device no longer
needs the leased IP address when the time ends up, and this device will also free the IP
address it had leased.

3.1.4 VPN (GRE)
SM3G III supports GRE VPN (Virtual Private Network) communication protocol. VPN is a technology
commonly used in different private networks between companies or groups. It allows the intranet
message to be transmitted using the public network such as Internet. Through VPNs, the user is able
to access resources on remote networks, for example, files, printers, databases, internal websites
and so on. You can refer to the following description of parameters to set up your VPN.
GRE Enable: Enable/Disable the VPN function for the SM3G III router.
Remote IP Address: The IP address of the remote VPN host.
Gateway: The IP address of Gateway in VPN.
IP/Subnet Mask: Set up the IP/Subnet Mask for VPN. The valid range for Subnet Mask is 8~32.
