This router is used in countries with German specific language. There is a manual of the device, but it's in German. However, I have accessed the file and gone through all the available options, but there wasn't anywhere specified about VPN. The only thing you have is in the Firewall section. There are some VPN passthrough modes. IF enabled, you can connect to VPN servers from your computer through the router. There is no other possibility to configure and manage VPN settings.
