FortiGate-7000F v6.2.7 special features and limitations

This section describes special features and limitations for FortiGate-7000F 6.2.7.

The FortiGate-7000F uses the Fortinet Security Fabric for communication and synchronization between the FIMs and the FPMs and for normal GUI operation. By default, the Security Fabric is enabled and must remain enabled for normal operation.

SDN connector support

FortiGate-7000 FortiOS 6.2.7 supports the following SDN connectors:

• Cisco Application Centric Infrastructure (ACI)
• Amazon Web Services (AWS)
• Microsoft Azure
• VMware NSX
• VMware ESXi
• Kubernetes
• Oracle Cloud Infrastructure (OCI)
• OpenStack (Horizon)

These SDN connectors communicate with their public or private clouds through the mgmt-vdom VDOM and may require routing in this VDOM to support this communication. Also, in some scenarios, these SDN connectors may not be able to correctly retrieve dynamic firewall addresses.

Default management VDOM

By default the FortiGate-7000 configuration includes a management VDOM named mgmt-vdom. For the FortiGate-7000F system to operate normally you should not change the configuration of this VDOM and this VDOM should always be the management VDOM. You should also not add or remove interfaces from this VDOM.

You have full control over the configurations of other FortiGate-7000F VDOMs.

Maximum number of LAGs and interfaces per LAG

FortiGate-7000F systems support up to 16 link aggregation groups (LAGs). This includes both normal link aggregation groups and redundant interfaces. A FortiGate-7000F LAG can include up to 20 interfaces.

IP multicast

IPv4 and IPv6 Multicast traffic is only sent to the primary FPM (usually the FPM in slot 3). This is controlled by the following configuration:

config load-balance flow-rule

edit 15

set status enable

set vlan 0

set ether-type ipv4

set src-addr-ipv4 0.0.0.0 0.0.0.0

set dst-addr-ipv4 224.0.0.0 240.0.0.0

set protocol any

set action forward

set forward-slot master

set priority 5

set comment "ipv4 multicast"

next

edit 16

set status enable

set vlan 0

set ether-type ipv6

set src-addr-ipv6 ::/0

set dst-addr-ipv6 ff00::/8

set protocol any

set action forward

set forward-slot master

set priority 5

set comment "ipv6 multicast"

end

High availability

You can use the M1 to M4 interfaces for HA heartbeat communication.

The following FortiOS HA features are not supported or are supported differently by FortiGate-7000F:

• Active-active HA is not supported.
• The range for the HA group-id is 0 to 31.
• Failover logic for FortiGate-7000F HA is not the same as FGCP for other FortiGate clusters.
• HA heartbeat configuration is specific to FortiGate-7000F systems and differs from standard HA.
• FortiGate-7000F HA does not support the route-wait and route-hold options for tuning route synchronization between FortiGate-7000Fs.
• VLAN monitoring using the config system ha-monitor command is not supported.

Virtual clustering

For information about virtual clustering limitations, see Limitations of FortiGate-7000F virtual clustering and Virtual clustering VLAN/VDOM limitation.

Shelf manager module

It is not possible to access SMM CLI using Telnet or SSH. Only console access is supported using the chassis front panel console ports as described in the FortiGate-7000F system guide.

FortiOS features not supported by FortiGate-7000F v6.2.7

The following mainstream FortiOS features are not supported by the FortiGate-7000F:

• Hardware switch
• IPv4 over IPv6, IPv6 over IPv4, IPv6 over IPv6 features
• GRE tunneling is only supported after creating a load balance flow rule, for example:

config load-balance flow-rule

edit 0

set status enable

set vlan 0

set ether-type ip

set protocol gre

set action forward

set forward-slot master

set priority 3

end

• EMAC VLANs are not supported.
• The FortiGate-7000 does not support configuring dedicated management interfaces using the config system dedicated-mgmt command or by enabling the dedicated-to management interface option. The purpose of the dedicated management interface feature is to add a routing table just for management connections. This functionality is supported by the FortiGate-7000 management VDOM (mgmt-vdom) that has its own routing table and contains all of the FortiGate-7000 management interfaces.
• Enabling the system settings option tcp-session-without-syn and configuring a firewall policy to accept sessions without syn packets allows FortiOS to add entries to its session table for sessions that do not include SYN packets. These sessions can only be load balanced by the NP7 processors if the dp-load-distribution-method is set to src-dst-ip-sport-dport (default) or src-dst-ip. If any other load distribution method is used, the sessions will be dropped. As well, the NP7 processors cannot load balance these sessions if they are accepted by a firewall policy with NAT enabled.

IPsec VPN

For a list of IPsec VPN features supported by FortiGate-7000F, see FortiGate-7000F IPsec VPN.

SSL VPN

Sending all SSL VPN sessions to the primary FPM is recommended. You can do this by:

• Creating a flow rule that sends all sessions that use the SSL VPN destination port and IP address to the primary FPM.
• Creating flow rules that send all sessions that use the SSL VPN IP pool addresses to the primary FPM.

For more information about FortiGate-7000F SSL VPN support, see SSL VPN load balancing.

Traffic shaping and DDoS policies

Each FPM applies traffic shaping and DDoS quotas independently. Because of load-balancing, this may allow more traffic than expected.

FortiGuard web filtering and spam filtering queries

The FortiGate-7000F sends all FortiGuard web filtering and spam filtering rating queries through a management interface from the management VDOM.

Web filtering quotas

On a VDOM operating with the Inspection Mode set to Proxy, you can go to Security Profiles > Web Filter and set up Category Usage Quotas. Each FPM has its own quota, and the FortiGate-7000F applies quotas per FPM and not per the entire FortiGate-7000F system. This could result in quotas being exceeded if sessions for the same user are processed by different FPMs.

Log messages include a slot field

An additional "slot" field has been added to log messages to identify the FPM that generated the log.

Special notice for new deployment connectivity testing

Only the primary FPM can successfully ping external IP addresses. During a new deployment, while performing connectivity testing from the FortiGate-7000F, make sure to run execute ping tests from the primary FPM CLI.

Display the process name associated with a process ID

You can use the following command to display the process name associated with a process ID (PID):

diagnose sys process nameof <pid>

Where <pid> is the process ID.
