How to redirect part of the traffic with a VPN?

Question

openvpn

I need to make a static (white) ip through services that provide such an opportunity through vpn in order to use Wake On Lan.
How can I make it so that only WoL packets go through this VPN, and all other traffic does not go through vpn.
There is an Asus RT-N12 router with custom Tomato firmware, it supports OpenVPN.

Answer 1

Add routes coming from the VPN server only to those hosts that you are going to wake up.

Answer 2

protocols can't be split.
