How to set up VPN for free WI-FI hotspot on Zyxel Keenetic Giga 2?

Question

VPN

A free WI-FI point from an Internet provider is organized at the entrance. I plan to connect to it through a Zyxel Keenetic Giga 2 router. As I understand it, this router can connect to WI-FI and there will be no problems (though I haven’t tested it yet).
The bottom line is that I don’t want to leak information to the provider and I want the data to be transmitted via VPN after connecting to a WI-FI point. At the level of the router, I have never done this. I have a license from F-Secure Freedome that I use as a program on my computer. But this option is not suitable, since there are several mobile devices at home that need to be connected to an already secure connection through a router.
Tell me how to be? Is it possible to somehow secure the connection at the router level?

Answer 1

Can. Your router can open tunnels using PPTP and L2TP protocols. Check with your VPN provider to see if they support these protocols.

Answer 2

A quick search reveals that F-Secure Freedome uses :
Our iOS product uses the IPSEC VPN standard. Android, Windows and Mac OS X products use the OpenVPN protocol.
The ports for iOS are:
UDP 500 - ISAKMP
UDP 4500 - ESP UDP encapsulation
The ports for Android, Mac and Windows are:
TCP/UDP ports in the range 2740 - 2749
TCP port 443
