Using Ip Policy Routing - ZyXEL Communications P-660HN-T1A Support Notes

Key Settings:
DHCP
If the P-660HN-T1A's DHCP server is enabled, the IP pool for the clients
Setup
can be any of the three networks.
TCP/IP
Enter the first LAN IP address for the P-660HN-T1A. This will create the
Setup
first route in the enif0 interface.
(2) Edit the second and third networks in Network -> LAN -> IP Alias by
configuring the P-660HN-T1A's second and third LAN IP
addresses.
Key Settings:
Active it and enter the second LAN IP address for the P-660HN-T1A. This
IP Alias 1
will create the second route in the enif0:0 interface.

11. Using IP Policy Routing


What is IP Policy Routing (IPPR)?
Traditionally, routing is based on the destination address only and the router
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. Network administrators can use IPPR to distribute
traffic among multiple paths. For example, if a network has both the Internet
and remote node connections, we can route the Web packets to the Internet
using one policy and route the FTP packets to the remote LAN using another
policy. See the figure below.
