P-660HN Series Support Notes Key Settings: DHCP Setup TCP/IP Setup If the P-660HN-T1A's DHCP server is enabled, the IP pool for the clients can be any of the three networks. Enter the first LAN IP address for the P-660HN-T1A. This will create the 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.

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

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,

using one policy and route the FTP packets to the remote LAN using another
policy. See the figure below.
