7.3 The Policy Route Screen
Click Configuration > Routing to open the Policy Route screen. Use this screen to see the configured
policy routes and turn policy routing based bandwidth management on or off.
A policy route defines the matching criteria and the action to take when a packet meets the criteria.
The action is taken only when all the criteria are met. The criteria can include the user name, source
address and incoming interface, destination address, schedule, IP protocol (ICMP, UDP, TCP, etc.) and
port.
The actions that can be taken include:
• Routing the packet to a different gateway, outgoing interface, VPN tunnel, or trunk.
• Limiting the amount of bandwidth available and setting a priority for traffic.
IPPR follows the existing packet filtering facility of RAS in style and in implementation. If you enabled IPv6
you can also configure policy routes used for your IPv6 networks on this screen.
Flag This indicates the route status.
U-Up : The route is up.
UC-Up Cache : The route is up and it is a cache entry.
!-Reject : The route is blocked and will force a route lookup to fail.
G-Gateway : The route uses a gateway to forward traffic.
H-Host : The target of the route is a host.
R-Reinstate : The route is reinstated for dynamic routing.
D-Dynamic (redirect) : The route is dynamically installed by a routing daemon or
redirect.
M-Modified (redirect) : The route is modified from a routing daemon or redirect.
Metric The metric represents the “cost of transmission”. A router determines the best route
for transmission by choosing a path with the lowest “cost”. The smaller the number,
the lower the “cost”. This is the route’s priority among the displayed routes.
Interface This indicates the name of the interface through which the route is forwarded.
The following fields are available if you click Address Mapping (1-1 SNAT) in the Routing Flow section
# This is the index number of the rule.
WAN Interface This shows the WAN interface through which the address mapping is forwarded.
Internal beginning IP This is the starting Inside Local IP Address (ILA).
External Beginning IP This is the starting Inside Global IP Address (IGA).
