Test purpose
I received question from partner that FortiGate product doesn’t support IPS load balance feature with HA A-A configuration.
I would like to take evaluation test to clear that point them for government project.
Configuration
2 x FortiGate 60B v3.00,build0726 (MR7)
NAT mode
Client PC connect to DMZ port. Target server connect to WAN1 port.
Test scenarios
Setup HA A-A configuration.
Enable IPS and logging feature with Protection Profile.
Enable Protection Profile on Firewall policy.
Install nmap to client PC which is port scan tool.
Run nmap, to send out the burst packets to “single” target server through FGT.
Check HA status, it also take a look the attack log on FGT.

Launch nmap tool on client PC.
Enter the target IP address.
Select scan profile.
Click the scan button to run.
Let’s wait to finish the port scan. It will takes couple of minutes.

Confirm when nmap process is stop.
Go to HA status menu to check the Intrusion detection counter.
It seems that 6 session was handle by slave device. But Master device IPS counter wasn’t same as slave. WHY?
Let’s see the attack-log.
Master
Slave

Go to the attack-log on both Master and Slave device.
It seems that TCP traffic is load balanced (6 each), but UDP traffic doesn’t.
Master
TCP traffic (6)
UDP traffic (3)
Slave
TCP traffic (6)

HA Guide v3.0 MR5
The primary unit receives all network traffic. All UDP, ICMP, multicast, and broadcast traffic is processed by the primary unit. The primary unit load balances virus scanning traffic, or optionally all TCP traffic and virus scanning traffic, among all cluster units.
I see… TCP traffic is load-balanced by Master and Slave device. But UDP traffic doesn’t. Reason why that number is different…
OK, Let send out TCP traffic only. How FGT works.
Please see next slide.

FGT does load-balance TCP traffic. (5 each)

12. Fortinet Confidential IPS load-balance with HA A-A
Go to attack-log both Master and Slave device.
TCP traffic is load-balanced by FGT.
It is very clear to me.
Master
TCP traffic (5)
Slave
TCP traffic (5)

Summary
FGT does support IPS load balance with HA A-A configuration for TCP traffic. (AV traffic as well)
Partner and Customer will clear about this point.

Configuration Points on this test.
Enable to load-balance feature through CLI.
# config sys ha
#(HA) set load-balance-all
The traffic is handle by weight-round-robin method, how to configure…
#(HA) set schedule weight-round-robin
The weighted round robin load balancing weight to assign to each cluster unit, e.g.…
# set weight 0 1 …. 10 1
Need more information? -> Please refer to HA Guide.
