[SOLVED] LAN Traffic not going into the configured Tunnel

RouterOS Beginner Basics
1

I have followed this how-to on how to setup my VPN tunnel : https://www.vpnunlimitedapp.com/help/manuals/mikrotik-ikev2-setup#id27
But I think their instructions are incorrect/outdated. Even though I configured the marking, something does not make sense and indeed, the traffic does not go through the tunnel.

Can someone help me understanding what is not correct in their example ? I am running 6.46.5,
The Tunnel is Active, so that part works.

Flags: X - disabled, D - dynamic, R - responder

Well, it turns out their instructions are wrong. The Mangle Rule should mark SRC address and not DST address.

I just tried this today and the same error is still on their instructions. Luckily I thought it looked wrong and it was a quick fix.
