D-Link DFL-700 - Manual (Page 21)

Routing
Click on System in the menu bar, and then click Routing below it, this will give a list of all
configured routes, it will look something like this:
The Routes configuration section describes the firewall’s routing table. DFL-700 uses a
slightly different way of describing routes compared to most other systems. However, we
believe that this way of describing routes is easier to understand, making it less likely for
users to cause errors or breaches in security.
Interface – Specifies which interface packets destined for this route shall be sent through.
Network – Specifies the network address for this route.
Gateway – Specifies the IP address of the next router hop used to reach the destination
network. If the network is directly connected to the firewall interface, no gateway address is
specified.
Local IP Address – The IP address specified here will be automatically published on the
corresponding interface. This address will also be used as the sender address in ARP queries.
If no address is specified, the firewalls own interface IP address will be used.
Proxy ARP – Specifies that the firewall shall publish this route via Proxy ARP.
One advantage with this form of notation is that you can specify a gateway for a particular
route, without having a route that covers the gateway’s IP address or despite the fact that the
route that covers the gateway’s IP address is normally routed via another interface.
The difference between this form of notation and that most commonly used is that there,
you do not specify the interface name in a separate column. Instead, you specify the IP
address of each interface as a gateway.
Note: The firewall does not Proxy ARP routes on VPN interfaces.
