Route Policy (also well known as PBR, policy-based routing) is a feature where you may need
to get a strategy for routing. The packets will be directed to the specified interface if they
match one of the policies. You can setup route policies in various reasons such as load balance,
security, routing decision, and etc.
Through protocol, IP address, port number and interface configuration, Route Policy can be
used to configure any routing rules to fit actual request. In general, Route Policy can easily
reach the following purposes:
Specify Interface
Through dedicated interface (WAN/LAN/VPN), the data can be sent from the source IP to the
destination IP.
Address Mapping
Allows you specify the outgoing WAN IP address (es) for an internal private IP address or a
range of internal private IP addresses.
Priority
The router will determine which policy will be adopted for transmitting the packet according
to the priority of Static Route and Route Policy.
Failover to/Failback
Packets will be sent through another Interface or follow another Policy when the original
interface goes down (Failover to). Once the original interface resumes service (Failback),
the packets will be returned to it immediately.
Other routing
Specify routing policy to determine the direction of the data transmission.
