DHCP Relay

Your gateway can act as a DHCP relay in case you would like to dynamically assign IP addresses from a DHCP

server other than your gateway’s DHCP server. Note that when selecting this option you must also change

GlobeSurfer

®

II’s WAN to work in routing mode. For more information, see section 6.6.10.2.

After selecting ‘DHCP Relay’ from the drop down menu, a ‘New IP Address’ link will appear:

Figure 5.53 IP Address Distribution - DHCP Relay

Click the ‘New IP Address’ link. The ‘DHCP Relay Server Address’ screen will appear:

Figure 5.54 DHCP Relay Server Address

8. Specify the IP address of the DHCP server.

9. Click ‘OK’ to save the settings.

•

Disabled

Select ‘Disabled’ from the combo-box if you would like to statically assign IP addresses to your network

computers.

Routing

You can choose to setup your gateway to use static or dynamic routing. Dynamic routing automatically adjusts how

packets travel on the network, whereas static routing specifies a fixed routing path to neighboring destinations.

‘Routing’

Select ‘Advanced’ or ‘Basic’ routing.

‘Device Metric’

The device metric is a value used by the gateway to determine whether one route is superior to another,

considering parameters such as bandwidth, delay, and more.

‘Default Route’

Select this check box to define this device as the default route.

‘Multicast - IGMP Proxy Internal’

IGMP proxy enables the system to issue IGMP host messages on behalf of hosts that the system discovered

through standard IGMP interfaces. IGMP proxy enables the routing of multicast packets according to the IGMP

requests of LAN devices asking to join multicast groups. Select the ‘Multicast IGMP Proxy Internal’ check-box to

enable this feature.

‘Routing Information Protocol (RIP)’

Select this check box to enable the Routing Information Protocol (RIP). RIP determines a route based on the

smallest hop count between source and destination. When RIP is enabled, select the following:

•

Listen to RIP messages - select ‘None’, ‘RIPv1’, ‘RIPv2’ or ‘RIPv1/2’.

•

Send RIP messages - select ‘None’, ‘RIPv1’, ‘RIPv2-broadcast’ or ‘RIPv2-multicast’.

Internet Connection Firewall

Your gateway’s firewall helps protect your computer by preventing unauthorized users from gaining access to it

through a network such as the Internet. The firewall can be activated per network connection.

To enable the firewall on this network connection, select the ‘Enabled’ check box. To learn more about your

gateway’s security features, please refer to chapter 5.3.

Additional IP Addresses

You can add alias names (additional IP addresses) to the gateway by clicking the ‘New IP Address’ link. This

enables you to access the gateway using these aliases in addition to the 192.168.1.1.

WAN Cellular

The WAN Cellular connection connects the GlobeSurfer

II to the Internet and other networks through the GSM and UMTS

mobile telecommunications standards. The ‘WAN Cellular Properties’ screen displays a summary of the connection properties

(see Figure 5.59).

5.2.5.1

General

The top part of the configuration window displays general communication parameters. It is recommended not to

change the default values in this screen unless you are familiar with the networking concepts they represent. Since

your gateway is configured to operate with the default values, no parameter modification is necessary. You can

configure the following general connection settings:

‘MTU’

MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission.

Manual, allows you to enter the largest packet size that will be transmitted. The recommended size, is 1492. You

should leave this value in the 1200 to 1500 range. To have the gateway select the best MTU for your Internet

connection, select Automatic (default setting).

5.2.5.2

Internet Protocol

Select one of the following Internet Protocol options from the ‘Internet Protocol’ drop down menu:

·

No IP Address

·

Obtain an IP Address Automatically

· Use the Following IP Address

REFERENCE MANUAL

Please note that according to the selection you make in the ‘Internet Protocol’ drop down menu, the screen will

refresh and display relevant configuration settings.

‘No IP Address’

Select ‘No IP Address’ if you require that this connection will have no IP address.

‘Obtain Address Automatically’

Select ‘Obtain Address Automatically’ if you require that this connection will try to obtain its IP address from a

DHCP server.

Figure 5.62 Internet Protocol Settings - DHCP

‘Use the Following IP Address’

The LAN connection is usually configured using a permanent (static) IP address. Your service provider should

provide you with this address, and subnet mask.

DNS Server

It is possible to specify IP addresses of primary and secondary DNS servers if for instance local domain names

should be handled by local name servers. Note that for the Cellular WAN interface, DNS servers are configured

separately.

If the ‘Internet Protocol’ setting mentioned above is set to ‘Obtain an IP address automatically’, then there is also

an option to configure the ‘DNS Server’ setting to obtain DNS Server settings automatically.

‘Routing’

Select ‘Advanced’ or ‘Basic’ routing.

‘Routing Mode’

When Advanced routing is selected, select one of the following Routing modes:

•

‘Route’ Use route mode if you want your GlobeSurfer 3G to function as a router between two networks.

•

‘NAPT’ Network Address and Port Translation (NAPT) refers to network address translation involving the mapping

of port numbers, allowing multiple machines to share a single IP address. Use NAPT if your LAN encompasses
