18.5 IP Static Routes
The ZyWALL has no knowledge of the networks beyond the network that is directly
connected to the ZyWALL. For instance, the ZyWALL knows about network N2 in the
following figure through gateway R1. However, the ZyWALL is unable to route a packet to
network N3 because it doesn't know that there is a route through the same gateway R1 (via
gateway R2). Static routes are for you to tell the ZyWALL about the networks beyond the
network connected to the ZyWALL directly.
