openvpn site to site linux and mikrotik

Hi
I have the following problem:
I configured a vpn with openvpn between a linux and a mikrotik
VPN is established and mikrotik network traffic to the linux network normally functions, but I can not traffic from linux network to mikrotik network.
Has anyone managed to travel in both directions with this architecture?

I can not ping the local LAN from linux to mykrotik local network
[root@sacicloudbnlmc openvpn]# ping 192.152.1.1
PING 192.152.1.1 (192.152.1.1) 56(84) bytes of data.

can I ping the local network from mikrotik to the local linux network
ping 10.51.96.1

Please post the config of your MikroTik by running an

/export hide-sensitive
