128 Establishing your network
Defining security gateway routing
Similar to network interfaces, the default gateway is defined by running the System Setup Wizard.
Each security gateway must have a default gateway assigned to one of the interfaces to route packets
properly.
See “Making system changes with the System Setup Wizard” on page 104..
Statically or dynamically configured routes
For smaller networks, it is usually easier to configure static routes by hand; there is normally only one
or two entries that you need to add to the security gateway’s routing table to accomplish this. However,
with larger networks, especially ones that are constantly changing, it might be more efficient to
implement a dynamic routing protocol. Regardless of the method you choose, the security gateway’s
routing table is updated anytime you either add routes manually, or configure the security gateway to
accept a dynamic routing protocol’s routing information.
Configuring static routes
Static routes are normally configured when you first set up the security gateway, or when you add new
routes to your existing network to which the security gateway is not directly connected. Once you
configure a static route, and save the changes, the new route takes effect immediately. Static routes
can be added or modified at any time, as these procedures do not require a reboot.
