How to change routes depending on the destination address on Mikrotik?

Question

VPN

There is a working tunnel with openVPN server. Mikrotik Opnvpn client. If I set the client's openvpn settings to ad default route, then all traffic goes through vpn and everything is fine. But that doesn't suit me.
I want traffic to go through the provider's gateway in all directions except for the ones I specify.
Tried to use this article. But firstly, nothing worked, and secondly, I don’t understand why I should add the entire subnet if I need only one ip address from it (or a group of ip addresses, depending on the situation, but in general it’s not an ip address, but a DNS name) .
Can you recommend articles or maybe implementation steps? Thanks
Given (addresses are fictitious)
White ip on the VPS server on the interest venet0: 1.1.1.1
OpenVPN on the VPS creates a network 192.168.200.0/24
as I understand it, the server ip becomes 192.168.200.1 by tun0
Mikrotik
Gray ip from the provider on ether1-gateway 10.1.66.171 Mikrotik
address in the local network 192.168.88.1
Accordingly, the DHCP server will unravel this and only this range.
When connecting to the openVPN server ip 192.168.200.6 I
propose to create a trial rule based on the site 2ip.ru 178.63.151.224
The current route table with a gateway from the provider

The route table in which all traffic goes through the openvpn gateway

It seems to me that I did not format the filter table correctly. I just made one article on the Internet, I don’t remember the address, here it is, maybe add something?

Answer 1

Another example that will come in handy for many: redirect all TCP connections to the OVPN gateway, and rkn.gov.ru to the default gateway.

/ip firewall address-list add list=RKN address=rkn.gov.ru
/ip firewall mangle add chain=prerouting protocol=tcp src-address=192.168.1.0/24 dst-address-list=RKN action=accept
/ip firewall mangle add chain=prerouting protocol=tcp src-address=192.168.1.0/24 dst-address=!192.168.0.0/16 action=mark-routing new-routing-mark=ovpn-route
/ip route add dst-address=0.0.0.0/0 gateway=ovpn-out1 distance=1 routing-mark=ovpn-route
