DEPLOYMENT GUIDE | Fortinet NGFW With Gigamon Inline
Overview
Fortinet's award-winning next-generation firewalls (NGFWs) provide highperformance, consolidated security for end-to-end protection across the entire network. Through awareness of applications, users, and content within network traffic, FortiGate NGFWs offer comprehensive protection against known and unknown threats (e.g., ransomware, malicious botnets, zero-day, and encrypted malware). They offer scalable throughput of advanced security services, flexible network interfaces, and performance based on Fortinet's powerful security processors. The FortiOS operating system ensures superior price, performance, and security efficacy.
The GigaVUE-HC2 Series is part of the GigaSECURE® Security Delivery Platform from Gigamon. The GigaBPS module in the GigaVUE-HC2 Series provides bypass protection to the Fortinet 3020 NGFWs. The module leverages two levels of bypass protection: physical and logical. Physical bypass preserves network traffic, failing to wire in the event of a power outage. Logical bypass protects against inline tool failures that could disrupt network traffic. Bidirectional heartbeats monitor the health of the inline tool, and in the event of a loss of link or loss of heartbeat, the Gigamon-HC2 can bypass traffic around the failing tool. Alternatively, the Gigamon-HC2 can bring down the network link so that the traffic can be routed to a redundant network path. GigaBPS pertains specifically to fiber links. For copper bypass, Gigamon offers a GigaVUE-HC2 copper TAP module.
This module includes electrical relays that can be used for bypass protection.
Aside from the above, deploying FortiGate and Gigamon together has the following benefits:
Solution Overview
The solution tested and described in this guide is based on a standard active inline network and tool deployment where two or more Fortinet appliances are directly cabled to one GigaVUE-HC2 chassis. The solution was tested with one GigaVUE-HC2 visibility node, one GigaVUE-FM Fabric Manager, and a FortiGate appliance.
This section covers the following:
nnUse Case
nnDeployment Prerequisites
nnArchitecture Overview
nnAccess Credentials
nnTraffic distribution for load sharing Improves the scalability of inline security by distributing the traffic across multiple FortiGate NGFW appliances, allowing them to share the load and inspect more traffic.
nnAgile deployment Adds, removes, and/or upgrades FortiGate NGFW appliances without disrupting network traffic; converting FortiGate NGFW appliances from out-of-band monitoring to inline inspection on the fly without rewiring.
nnOffload SSL Decryption Offloading SSL decryption to the Gigamon solution has proven to be high performance and increased overall efficiency of the tools.
Use Case 1: Inline Bypass (Virtual Wire Pair) Mode
Customers may need multiple FortiGate NGFW appliances to scale to the volume of traffic generated on their network. When the aggregate traffic exceeds the capacity of any single FortiGate NGFW, you must deploy multiple NGFWs with the ability to select traffic of interest, while bypassing the rest, and then distributing the selected traffic of interest among two or more NGFWs.
This distribution ensures all packets in a given TCP/UDP session go to the same group member. It also ensures that if any member of the group goes offline for any reason, the Gigamon-HC2 will distribute traffic among the remaining members, thereby ensuring availability of the security functions provided by the Fortinet NGFW.
Gigamon also gives the ability to test the configuration in an out-of-band mode called bypass with monitoring to allow complete confidence before going live. Switching from out-of-band to in-band is done by changing the setting in the inline network link, eliminating the need for physical change control procedures.

Deployment Requirements
The Gigamon plus Fortinet NGFW solution consists of the following:
nnGigaVUE-HC2 chassis with GigaVUE-OS 5.7.00 software, one PRT-HC0-X24, and one TAP-HC0-G100C0 (a BPS-HC0 line card can also be used). One SMT-HC0 Gigasmart card with inline SSL License (for Inline SSL only).
nnGigaVUE-FM version 5.7 software for GigaVUE-HC2 GUI configuration. nnTwo FortiGate NGFW appliances. This includes the following:
llFortiOS version 5.4.5 NOTE: This guide assumes all appliances are fully licensed for all features used, management network interfaces have been configured, and an account with sufficient admin privileges is used.
Architecture Overview This section presents the combined solution using a GigaVUE-HC2 inline bypass module with a FortiGate NGFW appliance. The reference architecture in Figure 1-1 shows each component's position in the overall network infrastructure, where all network components and inline security tools are connected directly to the GigaVUE-HC2. This section presents the combined solution.

Notice in Figure 1-1 that there is a sidedness to the architecture because data flows to and from Side A, where the clients reside, to Side B, where the internet and resources they request also reside. NOTE: It is essential that you connect the inline network and inline tool device bridge links to the GigaVUE-HC2 correctly relative to Side A and Side B so that traffic is distributed correctly to the Fortinet devices of the inline tool group.

Access Credentials
The default access credentials for the Gigamon GigaVUE-FM and FortiGate NGFW are as follows. Gigamon GigaVUE-FM access defaults:
nnUsername: admin nnPassword: admin123A! nnThere is no default management IP address
FortiGate NGFW access defaults:
nnUsername: admin nnPassword: leaveblank nnDefault management IP address: 192.168.1.99
NOTE: The GigaVUE-HC2 supports a graphical user interface (GUI) named H-VUE and a command-line interface (CLI). This document shows only the steps for configuring the GigaVUE-HC with GigaVUE-FM. For the equivalent H-VUE and CLI configuration commands, refer to the GigaVUE-OS H-VUE User's Guide and GigaVUE-OS CLI User's Guide, respectively, for the GigaVUE-OS 5.0 release.
Use Case 2: Inline SSL Solution With FortiGate
Secure sockets layer (SSL)/transport layer security (TLS) encrypted traffic introduces security blind spots and hides advanced threats leading to a surge in threat. Enabling SSL inspection on the security tools leads to degradation in performance and consumption of intensive CPU. GigaSECURE Inline SSL solution can be deployed to offload processor-intensive decryption functions from security tools such as an NGFW to increase threat inspection effectiveness. The underlaying solution is a validated design that allows for integrating TLS decryption/encryption services and performs the inline deep packet inspection and remediation on the decrypted traffic using the FortiGate NGFW.
Gigamon Inline SSL solution requires the connected inline tools to preserve the Layer 2 information. This allows to switch the traffic back to the appropriate inline network pair on which the traffic was received. When a firewall/Layer 3 router that performs NAT/PAT or an explicit proxy is connected as an inline tool, the MAC/IP/Layer 4 information gets swapped based on the policy configured on the inline tool. This traffic, when received back at Gigamon with swapped layer information, is not correlated and the sessions are not established to process further.
The solution outlined here mitigates the above limitation. After performing SSL/TLS decryption, the decrypted traffic from Gigamon hits Fortinet's virtual wire interfaces for deep packet inspection. FortiGate preserves the Layer 2 information in the virtual wire mode, once deep packet inspection is performed, the traffic loops back from the virtual wire interfaces and is reencrypted. The encrypted traffic is now forwarded back on the appropriate inline network pair to the connected FortiGate's routed interface to perform firewall, routing, and/or VPN functionality.
Architecture Overview
This use case illustrates deploying GigaVUE-HC2 device for SSL decryption and FortiGate firewall in virtual wire pair for inspection and in NAT/Route mode for routing the user's traffic to the internet, as illustrated in Figure 2-1.

DEPLOYMENT GUIDE | Fortinet NGFW With Gigamon Inline
The topology shows two separate instances of FortiGate: one as an inline tool and the other as a firewall. However, in the validation process, both of these modes are configured on a single NGFW hardware. A pair of interfaces are configured for virtual wire mode and are connected to GigaVUE-HC2 as an inline tool. FortiGate's Layer3 interface, which is configured in NAT/Route mode to route traffic, is connected to Gigamon on the inline network pair.
Configurations
This chapter describes the configuration procedures for the GigaVUE-HC2 and FortiGate NGFW as an inline tool group solution through Gigamon's GigaVUE-FM. The procedures are organized as follows: nnFortiGate Configuration: Virtual Wire Pair nnGigamon GigaVUE-HC2 Configuration: Inline Networks and Inline Tool Groups
The procedures configure the GigaVUE-HC2 to send live traffic to the FortiGate inline tool group, which will allow the use of FortiGate's NGFW protection capabilities.
Per best practices guidelines from FortiGate, the Gigamon GigaVUE-HC2 will be configured to distribute the traffic to the two Fortinet appliances in the inline tool group, assuring all traffic for any given client (by IP address) goes to the same member of the FortiGate inline tool group. NOTE: This chapter assumes that you have connected the Fortinet appliances directly to GigaVUE-HC2 as shown in Figure 1-1. You should configure all GigaVUE-HC2 ports that connect the Fortinet appliances as port type Inline Tool. Furthermore, you should configure the GigaVUE-HC2 inline bypass ports connected to the network devices as Inline Network ports. For specific instructions on how to complete these tasks, refer to the User Guides and Technical Documentation in the Customer Portal. NOTE: This chapter describes how to configure the FortiGate NGFW in NAT Mode using Virtual Wire Pairs. The FortiGate NGFW could instead be configured in Transparent Mode if needed.

21
DEPLOYMENT GUIDE | Fortinet NGFW With Gigamon Inline NOTE: This example uses a Pass All rule so any traffic going through the Inline Network(s) will be sent to the FortiGate(s) for inspection. If you want to selectively send traffic to the FortiGate(s), then use Flex Map; refer to the User Guides and Technical Documentation in the Customer Portal. 3. Click Deploy. Leave Default option Logical Bypass.
For Inline SSL decryption, just drag and drop Inline SSL map on the canvas and make sure the Inline Tool/Tool Group fall within the Inline SSL app. Make sure to click Deploy after placing the inline SSL App.
Changing Inline Network Traffic Path to Inline Tool
After configuring the maps, you need to change the traffic path for the inline networks from Bypass to Inline Tool. However, before setting the traffic path to Inline Tool, make sure that the inline tool ports are up. You can check the status of the ports by going to the Chassis View page in GigaVUE-FM by selecting Chassis from the main navigation pane. To change the traffic path from bypass to inline tool, do the following: 1. In GigaVUE-FM, select Inline Bypass > Edit. 2. Click one of the inline networks that you defined previously (refer to Step 2: Configure the Inline Network Group). 3. In the Configuration section, make the following changes:
nnSet Traffic Path to Inline Tool. nnUncheck Physical Bypass.

Summary and Conclusions
The previous chapters described how to deploy Gigamon GigaVUE-HC2 bypass protection with FortiGate NGFW appliances. This combined solution using the Gigamon GigaVUE-HC2 chassis for inline tool high availability and traffic distribution achieves the following objectives:
nnHigh availability of FortiGate NGFW because each inline security solution can be put into a Gigamon inline tool group with tool failover actions. The inline tool group can be optimized for each security need, regardless of whether the tool goes offline due to an outage or planned maintenance.
nnTraffic distribution to multiple FortiGate NGFW appliances for load sharing across multiple instances.
nnSeamless scalability for an increasing network infrastructure as well as the inline security tools to accommodate the additional traffic.
nnUltimate flexibility of adding new types of inline security tools without physical change control because all new tools are physically added to the GigaVUE-HC2 and logically added to the path through traffic flow maps.
