After I have done some speedtests on the FortiGate firewall I was interested in doing the same tests on a Palo Alto. That is: What are the throughput differences of IPv4 vs. IPv6, measured with and without security profiles, i.e., with and without threat prevention.
It turned out that the throughput is much higher than the official information from Palo Alto. Furthermore, I was not able to test the threat prevention at all, because non of my traffic (Iperf and mere HTTP) went through the antivirus engines. I have to test this again. However, here are the measured values so far:

I was interested in the performance of my FortiGate firewall when comparing IPv4 and IPv6 traffic. Therefore I built a small lab consisting a FortiWiFi 90D firewall and two Linux clients running Iperf. I tested the network throughput for both Internet Protocols in both directions within three scenarios: 1) both clients plugged into the same “hardware switch” on the FortiGate, 2) different subnets with an “allow any any” policy without any further security profiles, and finally, 3) activating antivirus, application control, IPS, and SSL inspection.

Seit wenigen Tagen bin ich glücklicher Kunde eines Telekom Glasfaseranschlusses. Mit satten 50/10 MBit/s rasen die Daten bei mir ein und aus. Neben der deutlich höheren Geschwindigkeit war ich aber auch an den Latenzen der beiden Anschlüsse interessiert und habe entsprechende Tests gemacht. Hier kommen die Ergebnisse.

I am very interested in statistics about the usage of IPv6 on Internet routers and firewalls. The problem is, that most routers/firewalls do not have unique SNMP OIDs for IPv4 and IPv6 traffic, but only the normal incoming/outgoing packet counters per interface. Therefore I am using two independent ethernet ports and cables between my outer router and my first firewall, one for IPv4-only and the other one for IPv6-only traffic. Now I have independent statistics for each protocol and can combine them in one summary graph. (Though I know that this will never be a “best practice” solution…)
