meaningful name). If the computer was assigned an IP address by the DHCP server, then the

Name will be appended by an asterisk.

•

IP Address

the IP address for the associated MAC address.

•

MAC Address.

Enter the MAC address of the computer’s network interface in the MAC

Configuring Multi Home LAN IP Addresses

If you have computers on your LAN using different IP address ranges (for example, 172.16.2.0 or

10.0.0.0), you can add “aliases” to the LAN port, giving computers on those networks access to the

Internet through the firewall. This allows the firewall to act as a gateway to additional logical

subnets on your LAN. You can assign the firewall an IP address on each additional logical subnet.

To add a secondary LAN IP address, follow these steps:

1.

Select

Network Configuration > LAN Setup

from the main/sub-menu.

2.

Click the

LAN Multi-homing

tab and the LAN Multi-homing screen displays.

The

Available Secondary LAN IPs

table lists the secondary LAN IP addresses added to the

firewall.

•

IP Address

. The “alias,” an additional IP address hosted by the LAN port of the firewall.

This address will be the gateway for computers on the secondary subnet.

•

Subnet Mask

. The IPv4 subnet mask that defines the range of the secondary subnet.

3.

In the

Add Secondary LAN IP Address

section, enter the additional IP address and subnet

mask to be assigned to the LAN port of the firewall.

4.

Click

Add.

The new Secondary LAN IP address will appear in the

Available Secondary LAN

IPs

table.

Figure 3-4

Note:

IP addresses on these secondary subnets cannot be configured in the DHCP

server. The hosts on the secondary subnets must be manually configured with

IP addresses, gateway IP addresses, and DNS server IP addresses.

Tip:

The secondary LAN IP address will be assigned to the LAN interface of the

firewall and can be used as a gateway by computers on the secondary subnet.

Configuring

S

tatic Routes

Static Routes provide additional routing information to your firewall. Under normal

circumstances, the firewall has adequate routing information after it has been configured for

Internet access, and you do not need to configure additional static routes. You should configure

static routes only for unusual cases such as multiple firewalls or multiple IP subnets located on

your network.

To add or edit a static route:

1.

Select

Network Configuration > Routing

from the main/sub-menu.

The Routing

screen displays.

2.

Click

Add

and the

Add Static Route

tab is displayed.
