REFERENCE MANUAL

Select one of the following options from the ‘IP Address Distribution’ combo-box:

·

DHCP Server

‘Start IP Address’

The ﬁrst IP address that may be assigned to a LAN host. Since the gateway’s default IP

address is 192.168.1.1, this address must be 192.168.1.2 or greater.

‘End IP Address’

The last IP address in the range that can be used to automatically assign IP addresses to LAN

hosts.

‘Subnet Mask’

A mask used to determine to what subnet an IP address belongs. An example of a subnet mask

value is 255.255.0.0.

‘WINS server’

If you use a Windows Internet Naming Service (WINS), specify the WINS server address in this

ﬁeld.

‘Lease Time In Minutes’

Each device will be assigned an IP address by the DHCP server for a this amount of

time, when it connects to the network. When the lease expires the server will determine if the computer has

disconnected from the network. If it has, the server may reassign this IP address to a newly-connected computer.

This feature ensures that IP addresses that are not in use will become available for other computers on the

network.

‘Provide Host Name If Not Speciﬁed by Client’

If the DHCP client does not have a host name, the gateway will

automatically assign one for him.

·

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:

·

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

computers.

5.2.2.7

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’.

‘Routing Table’

Allows you to add or modify routes when this device is active. Use the ‘New Route’ button to add a route or edit

existing routes.

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.

5.2.2.9

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.

LAN Ethernet

A LAN Ethernet connection connects computers to GlobeSurfer

®

II using Ethernet cables, either directly or via network hubs

and switches.

Figure 5.24 LAN Ethernet Properties

Clicking the “Settings” button at the bottom-right of the connection’s Properties window, will open its Conﬁguration window:

Note that available conﬁguration options may vary depending on if the LAN Ethernet interface is part of a bridge or not.

5.2.3.1

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:

‘Physical Address’

The physical address of the network card used for your network. Some cards allow you to change this address.

‘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).

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

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. Figure 5.27 Internet Protocol

Settings - No IP Address

Figure 5.27 Internet Protocol Settings - 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 5.28 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.

5.2.3.3

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.

5.2.3.4

IP Address Distribution

The ‘IP Address Distribution’ section allows you to conﬁgure the gateway’s Dynamic Host Conﬁguration Protocol

(DHCP) server parameters. The DHCP automatically assigns IP addresses to network PCs. If you enable this

feature, make sure that you also conﬁgure your network PCs as DHCP clients. For a comprehensive description of

this feature, please refer to section 6.6.10.
