Policy-based routing
Normally, a routing device determines how to route a network packet based on its destination
address. However, you can use policy-based routing to forward the packet based on other criteria,
such as the sourceof the packet. For example, you can configure the IX20 device so that high-priority
traffic isrouted through the cellular connection, while all other traffic is routed through an Ethernet
(WAN) connection.
Policy-based routing for the IX20 device usesthe following criteria to determine how to route traffic:
n
Firewall zone(for example, internal/outbound traffic, external/inbound traffic, or IPSec tunnel
traffic).
n
Network interface(for example, the cellular connection, the WAN, or the LAN).
n
IPv4 address.
n
IPv6 address.
n
MACaddress.
n
Domain.
n
Protocol type (TCP, UDP, ICMP, or all).
The order of the policies is important. Routing policies are processed sequentially; as a result, if a
packet matches an earlier policy, it will be routed using that policy’s rules. It will not be processed by
any subsequent rules.
