OpenVpn To PPTP between 2 microtik

Good evening everyone
A question
I have two routers connected in pptp via ipsec.
One of these microtiks has an OPENVPN link to a server, is there a way to include this link in the PPTP link between the two microtiks?
In practice from the other site I need to see the vpn of the first

ROUTER A
WAN: 1.1.1.1
LAN: 192.168.10.0/24
ROUTER LINK OPENVPN TO PFSENSE

ROUTER B
WAN: 2.2.2.2
LAN: 192.168.6.0/24

ROUTER B ees the lan 192.168.10.0, but not the OPEN vpn.

If I connect in pptp from windows to router A I also see the OPEN VPN

Is there any rule to set?

First let me check if i got you right
router 1 can talk with router 2 via pptp, router 2 (lets say) is connected to a server with openvpn
and you correctly unable to reach the server from router 1.

If you want to reach the server from router 1 you have 2 options.
1.easy - create static route on the server to the subnet of router 1 via router 2, and on router 1 create static route to the server subnet via router 2.
2. harder - create a tunnel (of your choose) to the server from router 1.
