Mikrotik as OpenVPN client, lan behind mikrotik?

RouterOS Beginner Basics
1

Sorry for a silly question.
I have an ASUS router as an openvpn server (192.168.3.1), and a mikrotik as a client (192.168.7.1)
Mikrtoik successfully connects to ASUS and gets assigned IP 10.8.0.17
Everything can be pinged from the mikrotik and lan behind mikrotik to asus and behind asus (192.168.7.0 > 192.168.3.0)
Yet from the Asus side the network 192.168.7.0 including the mikrotik itself cant be pinged. mikrotik only responses on its VPN ip (10.8.0.17)

What should I do so I can access the LAN behind the mikrotik from the ASUS network?

Assuming near default Mikrotik configuration.

Likely option is you need to make the openvpn client interface on the Mikrotik a member of the LAN interface list.

The following seems likely already done, you need to have routes on the Asus telling it the mikrotik lan network IP’s are via the openvpn client at 10.8.0.17

If the mikrotik openvpn client is currently a member of the WAN interface list, you perhaps need to decide if that is what you actually want.
