If you later want to change it you need to configure both sides again. Using a policy-based setup, the networks on both sides are defined statically in the configuration and during the negotiation of the IPSEC VPN tunnel. In the blue corner the challenger of today Barracuda CloudGen Firewall and in the red corner Fortinet’s FortiGate Next-Gen Firewall.Ī year or 2 ago, I already had worked on this and I had a configuration documented but that never got onto the blog. Recently, I worked on a project to connect 2 firewalls, I know quite well, using IPSEC. Connection vendor A with vendor B or with open source implementation C can be a daunting task and some say: “it is black magic”. This leads to the implementations of the standard to be ever so slightly out of sync with each other. It is a standard developed in a large committee to create something that was versatile but it made it also quite complex. ‘IPSEC’ is not the most user-friendly protocol in the world. They will think about the numerous times trying to get tunnel up or debugging a stability issue with one of the tunnels. At the same time, if you mention the word ‘IPSEC’ to a lot if not most IT Pro’s they will cringe.

Feel free to share it with your network.To connect different locations with each other the word ‘IPSEC’ comes up very quickly. In my case, there are related to bandwidth. You need to define the channels you want to include. Select the one you need, and PRTG will create a sensor accordingly. PRTG will do a meta-scan and discover all available VPN tunnels.

For writing this article, I run my workloads on powerful mini PC - Intel NUC powered with the CPU i7 the latest generation, 64 GB RAM DDR4, 256 M.2 SSD. For each sensor, you can define up to ten channels. You can create one new sensor per table row.

The SNMP Custom Table sensor monitors entries from a table that is provided via SNMP. You would need to use SNMP Custom Table Sensor. There is a trick on how to monitor specific VPN tunnels. If you would like to monitor a certain VPN tunnel that is connecting Berlin and your hometown, you wouldn’t be able to do so. When it comes to VPN, these sensors show only UP and DOWN sensors, nothing else.
