DI-1162 Remote Access Router
I.In the case where the destination resides in the same IP network on the LAN, the routing engine never acts on the packet and it is sent directly to the destination through the LAN.
II.In the case where the destination resides on a different IP network on the LAN (which can happen when Multiple Home Configuration is set up), the router will send out an ARP request to obtain the MAC address of the destination computer (or router) and deliver the packet. Note that defining Static ARPs can speed up delivery since the router won’t need to send out an ARP request.
III.In the case where the router finds a match in the routing table (which includes IP Static Routes), it uses the Gateway address and Interface numbers to identify the correct Remote Network Profile to use to dial out. From the Remote Network Profile, the router gets the telephone number and other information and dials out, establishes a connection and delivers the packet. If you have a connection to the Internet, it is very important that you define the default next hop router in the IP Static Routes submenu of the console program as your ISP (see the IP Static Routes section of this manual for more detailed configuration information). This is because if a user on your LAN makes a request to download a web page for the first time, for instance, since it is the first time, the
IV. In the case where there is no match for the destination IP address in the routing table, and no default next hop router is defined, the packet will be dropped and no action will be taken.
