So I created an IKEv2/IPSec tunnel for VPN and it worked. I can specify local IPs to put them on VPN with .
I want to go further and make a proxy IP:Port to enter Chrome/Firefox, that it will put me on that VPN above. So it will be browser-wide VPN and I won't have to add/remove additional clients into my vpnclients list unless I want system-wide VPN.

How can I accomplish that? Is it possible?

I tried natting, marking routing forward to socks5 proxy I created but didn't work.... Still couldn't figure out how to forward it to my vpn.
