Openvpn client route puzzle for ninjas☀️

Challenge for net ninjas I have a server at 192.168.8.144 this is controlled by glinet flint 2 (192.168.8.1) NORDVPN

Currently on VPN controlled by MACadress device

The device 192.168.8.144 is a server and it has two interfaces,
Both of these faces are using the same lan under the same ip of;

192.168.8.144

eno1 - I WANT ALL THIS TRAFFIC TO GO TO NORD VPN
part of 192.168.8.144
and

tailscle0 - I want all this traffic to go to my router unaffected by my my router gatkept address that

also part of 192.168.8.144 but under the interface 111.111

BOTH of these interfaces sit on 192.168.8.144 in an instance of True Nas Scale

question.
how do I tell openvpn client to allow traffic from one of the two interfaces residing on the target device (192.168.8.144 )

as inside of Glinet flint 2 GUI I cant see anything but 192.168.8.1

inside luci all I see is 192.168.8.144

Thank you

This is what is happening

When Nord is locking down 192.168.8.144 the traffic outbound for tailscale0 drops from 900mbps

to 120mbps

so this is what I want to happen; the vpn be on 192.168.8.144 but allow tailscal0 device to bypass/ignore/disable/route though, be allowed unaffected by nords vpn service.
