How does FortiGate policy route work?

Policy route options define which attributes of a incoming packet cause policy routing to occur. If the attributes of a packet match all the specified conditions, the FortiGate unit routes the packet through the specified interface to the specified gateway. To view policy routes go to Router > Static > Policy Routes.

What is policy based routing FortiGate?

You can use the incoming traffic’s protocol, source or destination address, source interface, or port number to determine where to send the traffic. When a packet arrives, the FortiGate starts at the top of the policy route list and attempts to match the packet with a policy.

How does policy based routing work?

Policy-based routing is a process whereby the device puts packets through a route map before routing them. The route map determines which packets are routed to which device next. You might enable policy-based routing if you want certain packets to be routed some way other than the obvious shortest path.

What is the expected behavior when the stop Policy Routing action is used in a policy route?

What is the expected behavior when the Stop policy routing action is used in a policy route? FortiGate will skip over this policy route and try to match another in the list. FortiGate will route the traffic based on the regular routing table.

What is local policy-based routing?

Local policy-based routing allows you to configure a defined policy for IPv6 traffic flows, lessening reliance on routes derived from routing protocols. All packets received on an interface with local policy-based routing are configured in route maps.

What is Blackhole route in FortiGate?

For more information on the ACL, see the router chapter of the FortiGate CLI Reference. Blackhole Route. A blackhole route is a route that drops all traffic sent to it. It is very much like /dev/null in Linux programming. Blackhole routes are used to dispose of packets instead of responding to suspicious inquiries.

What is stop Policy Routing in FortiGate?

If no policy route matches the packet, the FortiGate unit routes the packet using the routing table. In this scenario you can use “”Stop Policy Routing” feature to tell FortiGate to use route in the routing table to forward the traffic instead of attempting to match the Policy Routes listed in the Policy Routing Table.

What is ISDB route?

ISDB is acting as policy route. So to verify ISDB route: This means, that for ISDB routes are applying same rules as for policy-routes. Mainly, that in order for policy-route to work, it is necessary to have valid route in the routing-table for the outgoing interface.

What is PBR firewall?

Policy Based Routing (PBR) is a feature that has been supported on Cisco Routers for ages. However, Cisco ASA firewalls didn’t support this until version 9.4. 1 and later. Finally Cisco acknowledged the usefulness of PBR on firewall devices and has implemented this on ASA as well.

What is Cisco PBR?

Policy-Based Routing (PBR) is a very popular feature in Cisco routers; it allows the creation of policies that can selectively alter the path that packets take within the network. PBR provides a method to forward packets by overriding the information available in the IP routing table.

What is an MTU black hole?

What is a PMTU Black Hole? A PMTU black hole is where the ICMP message doesn’t reach the sending host to inform it that it needs to adjust its MTU.

Can a blackhole route prevent routing loops?

To prevent the routing loops, you can configure a 32-bit-mask blackhole route bound for addresses in the address pool on the NGFW. The NGFW discards packets whose destination addresses match the blackhole route. The 32-bit-mask blackhole route is needed when static mapping is enabled on the NGFW.

What is a policy route in FortiGate?

For example: traffic from the client to the servers enters the FortiGate on either port1 or port2, and a policy route is defined to match traffic that is sent from the servers’ subnet to port2. The return traffic will not be checked against the policy route.

When do I need to filter traffic through FortiGate?

In some FortiGate deployments, it may be necessary to have a certain type or source of traffic filtered through a different network connection. In other words, a specific protocol or IP will sometimes need to be sent to a destination other than the default gateway or route.

What is FortiGate multiple Connector support?

What VPN services are available with FortiGate?
