Run VPN for specific application

Hi! I’m trying to figure out how should I approach this in my Mikrotik Hex GR3.

I do own an internet cafe and currently the specific Game/Application doesn’t run without a VPN connection.

I have run a NordVPN with IPSEC before but that is for all the PC connected to that network.

So what I would like to do is have my NordVPN enabled when the specific Game/Application is running.

Thank you for any insights!

Unfortunately, there’s no trigger to automatically fire up NordVPN, like when you use a specific port or IP address. Why can’t you just leave NordVPN on all the time and, say, only route certain traffic through it?

Is this gaming done through wired ports or wifi.
Larsa has the right idea.
If done through ports, then connect to a switch and control the switch for nordvpn only, if done by wifi assing a vlan SSID to the wLAN for nordvpn only

anyone who can suggest/build a step by step guide on this topic? Any way to create routes for specific internal IPs and/or create a switch to enable-disable VPN at router gateway level?

Nope, you dedicate one vlan to be connected to the VPN at all times.
Users can join that VLAN by accessing an SSID for that purpose ( A WLAN connected to the VLAN ) or they connect to a port on a switch ( and join same vlan )
