FortiGate PPPoE inside a VLAN

Some providers (like init7.ch which already uses the Swisscom XGS-PON) do encapsulate their PPPoE traffic into a VLAN Tag (802.1Q or Q-Tagged). The reason for this is, that in the majority of the cases the provider is using a layer 2 network (last mile) of another provider, which uses VLAN tagging to differentiate the traffic to different service providers.

The configuration of the FortiGate is not too complicated in those cases. It is even possible to make the whole configuration directly off the WebGUI.

BOLL Konsolenkabel

Netzwerk & Security Administratoren kennen die Problematik. Um Zugriff auf eine serielle Konsole zu bekommen, benötigt es einen Adapter, da kaum mehr ein Notebook einen alten DB9 (DE-9) Anschluss hat. Kein Hersteller liefert aber ein USB Konsolenkabel direkt auf RJ45 Ports, welche heute bei praktisch allen Netzwerk & Security Devices der Standard sind.

Die nervigen Adapter und die teilweise mühsame Treiber Unterstützung hat uns bewogen, ein eigenes Boll Konsolen Kabel entwickeln zu lassen. Folgende Bilder illustrieren das schön:

PaloAlto EDL Hosting Service

If you want to configure rules for Saas services on the PaloAlto Firewall, you can do this using the App ID for the particular service, or you can use the IP addresses, Domains or URLs of the service in the policy.

However, since Saas services typically do not use only one IP address, domain or URL, and since these can change dynamically, it requires a dynamic list that is constantly updated automatically.

PaloAlto offers this service as «EDL hosting service». External Dynamic Lists (EDL) are dynamic lists that can contain a list of IP addresses, domains or URLs. These lists are periodically queried by the firewall and updated accordingly. These EDL lists can then be used in various policies. Due to the automatic update of the lists, they are always up to date. There is also no need to commit the configuration if the list changes.

Fortigate und Swisscom TV – zum dritten

Unser letzter Beitrag zur Konfiguration einer Fortigate, um zuhause auch Swisscom TV durch die Fortigate zu bekommen, ist schon eine zeitlang her. Deswegen hier mal wieder ein aktueller Beitrag mit einer Fortigate auf FOS 7.0.0 (der auch mit 6.4.5 getestet wurde).

In diesem Beispiel hängt die Swisscom TV Box am DMZ Port der Fortigate und bezieht von dort eine DHCP Adresse, welche per DHCP Reservation fixiert wird:

FortiGate hardware acceleration step-by-step troubleshooting

One of the very powerful features of FortiGate hardware appliances is the hardware acceleration chipset included in the hardware platform. This allows to forward traffic in specific situations directly from the incoming interface to the outgoing interface without passing the CPU of the system. This can safe a huge amount of system load on your FortiGate.

In most cases, hardware acceleration is working flawlessly. But in some very rare cases, hardware acceleration may cause problems. Or the hardware acceleration is not working at all and the packets have to be handled by the CPU of your FortiGate.

This guide will lead you through the important troubleshooting steps.
