to in the “

Routing defines the rules determining how IP packets reach their destination on the Internet.
The Air 4240 supports “static routing” where you specify the target IP addresses and how to
get to them. To specify the type of routing to use and set the necessary parameters, use the
ROUTING
menu of the Web interface.
To define a static routing rule, go to Static Routing under the ROUTING menu of the Web
interface. You now need to enter a destination IP and how to get to it.
•
Destination IP:
Enter the IP address of the destination
•
Netmask:
Enter the Netmask for the destination IP address
•
Connection:
Enter the interface that will be used for the data transfer. It should be set to
“lan” for local IP addresses and “wan” for remote IP addresses.
• Gateway:
Enter the IP address of the host that can transfer the data to the “
Destination
IP
”. This can be a WAN IP or a LAN IP address depending on the connection type.
•
Metric:
In this field, you can specify the number of hops (how many gateways the data
needs to go through) to get to the destination IP.
