• Use the
Static Route
screens (see
) to list and
configure static routes.
15.1.2 What You Need to Know
Policy Routing
Traditionally, routing is based on the destination address only and the ZyWALL
takes the shortest path to forward a packet. IP Policy Routing (IPPR) provides a
mechanism to override the default routing behavior and alter the packet
forwarding based on the policy defined by the network administrator. Policy-based
routing is applied to incoming packets on a per interface basis, prior to the normal
routing.
How You Can Use Policy Routing
• Source-Based Routing – Network administrators can use policy-based routing to
direct traffic from different users through different connections.
• Bandwidth Shaping – You can allocate bandwidth to traffic that matches routing
policies and prioritize traffic (however the application patrol’s bandwidth
management is more flexible and recommended for TCP and UDP traffic). You
can also use policy routes to manage other types of traffic (like ICMP traffic) and
send traffic through VPN tunnels.
Note: Bandwidth management in policy routes has priority over application patrol
bandwidth management.
• Cost Savings – IPPR allows organizations to distribute interactive traffic on high-
bandwidth, high-cost paths while using low-cost paths for batch traffic.
• Load Sharing – Network administrators can use IPPR to distribute traffic among
multiple paths.
• NAT - The ZyWALL performs NAT by default for traffic going to or from the
WAN
interfaces. A routing policy’s SNAT allows network administrators to have traffic
received on a specified interface use a specified IP address as the source IP
address.
Note: The ZyWALL automatically uses SNAT for traffic it routes from internal
interfaces to external interfaces. For example LAN to WAN traffic.
Static Routes
The ZyWALL usually uses the default gateway to route outbound traffic from
computers on the LAN to the Internet. To have the ZyWALL send data to devices
not reachable through the default gateway, use static routes. Configure static
routes if you need to use RIP or OSPF to propagate the routing information to
other routers. See
for more on RIP and OSPF.
