multi openvpn servers with fw rules

[tl5k5]

Hello all,
I'm trying to configure two openvpn servers on my opnsense box.
VPN1 = tunnels to the end point LAN-x and does connect to all on LAN-x.
VPN2 = I need it to only have access to 1 server in LAN-x.
I thought I could have VPN2 tunnel to LAN-y and set rules to only allow LAN-y to access the single LAN-x server, but I can not get this to work.
Anyone have any guidance to get a secondary VPN to only have access to a single server on the LAN?

Thanks!
