Recently installed openWRT

On my x86 router I have

1 wan port

Used to get out to the internet

1 lan port

Used for Connected to a switch for clients to receive DHCP leases and connect clients to the internet as well as each other

What I need help with:

Because my VPN providers info is kind of outdated for this topic,

I need a “step by step” guide (OpenWRT 23.05.3) for:

-setting up wireguard VPN provider (to which I have

the config file (.conf)) in a way that allows me to funnel the traffic of only one lan IP address through it

-While maintaining The internet services of all other clients through the regular Wan internet connection

Please understand, this split tunneling must be done on one physical interface

I’ve tried sitting at wireguard myself with split tunneling

All the advice is either on one or the other

I have a VPN provider

I’d like to use it on my router

But for one IP address on my local area network which can’t easily use your typical installer
