Default LLB Link Policy routeDefault routes have lower priority than configured routes. Select Add another route and set Destination to 0.0.0.0/0 and Target to the network interface ID of the private interface. Technical Tip: Policy routes with multiple ISP - Fortinet Community FortiGate FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic. ISP-2 learn the public IP Range from the FortiGate over ISP-1. By default, the redistributed default route is with the metric of 10. First lets create this in the GUI. Thanks again for the info, tanr. Solution 1) Interface configuration. In the table, select the policy route. Enable Router > Policy Route, and click OK. By default, distance for static routes is 10, for ISP is 20, for OSPF is 110, for EBGP is 20, and for IBGP is 200. The FortiGate has multiple SD-WAN links and has formed BGP neighbors with both ISPs. route created. The Forums are a place to find answers on a range of Fortinet products from peers and product experts. The gateways reside in different datacenters, but have a full mesh network between them. # config system interface edit "wan" set vdom "root" set mode dhcp Configured as dhcp so default route would be pushed set allowaccess ping fgfm set type physical set role wan set snmp-index 1 next edit "wwan" set vdom "root" Both the internet and MPLS terminates to an HA pair of Fortigates. Set High-Priority Traffic Guarantee. The route with the lowest value in the priority field is considered the best route, and it is also the primary route. Rule 1 denies the specific subnet, but unless the rest of the IPv4 range is defined afterwards (with implicit allow) then it blocks everything. Create dead gateway detection entries. Display policy routes. Now I can apply similar rules to the IPSEC neighbours. ISP1 is used primarily for outbound traffic, and has an SD-WAN service rule using the lowest cost algorithm applied to it. Rule 2 uses set le 32 to match the whole IPv4 range (that isn't previously blocked by rule 1). The traffic is matching the FIB and uses and outbound interface accordingly. Creating a default route Go to VPC Dashboard > Route Tables and select Create Route Table. I want to setup the sites to failover to the other sites internet connection via the MPLS. Set the default gateway: config system route edit <seq_num> set device <port> set gateway <gateway_ip> end where: <seq_num> is an unused routing sequence number starting from 1 to create a new route. Set Apply Shaper to Per Policy. I am leaving the AD at 10 - which is default. Create a Second Virtual NIC for the VM There is also a route out port2 (also the trusted/internal interface) with the VNET prefix as the destination. In this topology, a branch FortiGate has two SD-WAN gateways serving as the primary and secondary gateways. FortiGate will add this default route to the routing table with a distance of 5, by default. Take a look to the provider BGP Networks. I am running a Fortigate 1240b on FortiOS 5.2.3, and when I create a virtual wan link to do ECMP load balancing between multiple ISPs I set a default route for the virtual wan link, but then cannot set another default route for an ISP link that I do not want in the load balance group. The distance metric is configurable for static routes and OSPF routes, but not for ISP routes. Therefore, take caution when you are configuring an interface in DHCP mode, where Retrieve default gateway from server is enabled. You could probably use communities at the PE/CPE connected to the branches and manipulate BGP metrics based on the community. In order to change the metric for the default route, you can use the following options (CLI): # config router ospf. Change the display options for HUB1 to make policy routes visible in the GUI. The lower priority primary connection will be used when the FortiGate is not sure which default gateway to use for an outbound connection. config router static edit 1 set device "wan1" set gateway 10.160..160 next edit 2 set device "wan2" Solution The solution is to configure the two default routes with the same distance, but with different priorities, as shown below. Check Max Bandwidth and set to 1048576 Kb/s. The virtual network is created as well and forces traffic for additional protected networks to pass through the FortiGate-VM. The default route 0.0.0.0/0 points to the FortiGate-VM internal IP address. <gateway_ip> is the default gateway IP address for this network. In the menu on the left, select Networking. Create a new inbound port rule for TCP 8443. To create a new default route, go to Network > Static Routes. To move a policy route in the CLI: config router policy move 3 after 1 end Typically, you have only one default route. You can have as many default routes as you want and they have the same distance but varying priorities. The Display Options dialog box is displayed. So, the solution was in the prefix list. Having this route in place allows the FortiGate-VM to respond. As you can see the FortiGate learn the default Gateway from both ISPs but the Gateway 100.100.100.254 (ISP-1) is the best. 3. Go to Network > Interfaces, select port 2, and click Edit. In the web GUI, go to Policy & Objects. In the second-from-left pane, click Display Options. set default-information-metric-type . Check Guaranteed Bandwidth and set to 1000 Kb/s. Press OK - and Bam! This provides a route to any additional subnets that may be created. Fortinet Community Knowledge Base FortiGate Drag the selected policy route to the desired position. Example Fortigate Port 2 Interface You can have two (or more) default static routes, but they must both have the *same* distance, but with different priorities. Set VPC to the private subnet and select Yes, Create . Set Traffic Priority to High. Navigate to network - static routes - and create a new one. We can check that the route has been created and is the routing table by going to monitor - routing monitor. Select Add inbound port rule. Please follow the steps to allow HTTPS in FortiGate: Login to FortiGate using your username and password. This article describes how to configure this feature. To display policy routes: In the tree menu under Managed FortiGates, select HUB1. ISP-2: <shorted> *> 100.200.100./24 192.168.1.2 0 65100 65301 i <shorted>. Additionally, there are also two static routes: Azure uses the 168.63.129.16 address for various services. Go to the Azure portal, and open the settings for the FortiGate VM. Set Type to Shared. When SLAs for ISP1 are not met, it will fail over to the MPLS line. Policy routing multiple default gateways on Fortigate I have two locations each with their own internet connection and joined by an MPLS. This catches all traffic except for the virtual network traffic and sends it to the FortiGate-VM for inspection. . Priority of a route in FortiOS is the equivalent of "cost" on other devices. That way they both stay in the routing table and the policy route can force you to one or the other interface. Now we will just insert the needed info. Multiple default routes are present as per the above configuration, where the wan interfaces are not part of the sdwan, the FIB lookup takes place and it is not guaranteed that the traffic is forwarded via the sdwan member configured in the rule. Edit the existing High Priority Traffic Shaper. If the static route list already contains a default route, you can edit it, or delete the route and add a new one. This example shows how route-maps and service rules are selected based on performance SLAs and the member that is currently active. Go to Network > Policy Routes. Mark the HTTPS checkbox under Administrative access > IPv4 and click OK. Select the new route, then select the Routes tab, then select Edit. Select Traffic Shapers. Do you know if link health monitors will remove policy routes from the routing table, similar to how static routes Loading. Sample Command: set default-information-originate enable. Select Add. <port> is the port used for this route. If the SP uses different RD for the VRF towards the hubs it would be possible to have several default routes as the VPNv4 prefixes would be unique when the RD is prepended onto the 0.0.0.0/0 prefix. This will take precedence over any default static route with a distance of 10. The network interface is listed, and the inbound port rules are shown. set default-information-metric 1 <----- It is possible to use metric if needed. Use the default value of 0 for the priority of the connection you wish to be the primary and a higher priority for the secondary connection. Potential points to check for OP: 1, Make sure the interface has "Retrieve default gateway from server" enabled 2, If there's a different default gateway route already configured for some other interface, keep in mind the distance settings. Set Destination to Subnet and leave the destination IP address set to 0.0.0.0/0.0.0.0. The PE/CPE connected to the branches and manipulate BGP metrics based on SLAs.
