Static Route
This chapter shows you how to configure static routes for your ZyWALL.
22.1 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.
Figure 221 Example of Static Routing Topology
22.2 IP Static Route
Click ADVANCED > STATIC ROUTE to open the IP Static Route screen (some of the
screen’s blank rows are not shown).
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 default route is disabled after you change the static WAN IP address to a dynamic WAN
IP address.
