Static Route
This chapter shows you how to configure static routes for your ZyWALL.
23.1  IP Static Route   
Each remote node specifies only the network to which the gateway is directly connected, and 
the ZyWALL has no knowledge of the networks beyond. For instance, the ZyWALL knows 
about network N2 in the following figure through remote node Router 1. 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 remote node Router 1 (via gateway Router 2). The static routes are for 
you to tell the ZyWALL about the networks beyond the remote nodes.

23.2  IP Static Route  
Click ADVANCEDSTATIC ROUTE to open the IP Static Route screen (some of the 
screen’s blank rows are not shown). 
Note: The first two static route entries are for default WAN1 and WAN2 routes on a 
ZyWALL with multiple WAN ports; the first static route entry is for the default 
WAN route on a ZyWALL with a single WAN port. You cannot modify or delete 
a static default route. The name of the default static route is left blank unless 
you configure a static WAN IP address.
