OpenVPN and routing

[Maksims]

Good day, community!
May be someone can give me some advices where to search a problem.

I have a OpenVPN connection to my PfSense: Mikrotik -> Pfsense.
OpenVPN is up & running.
Mikrotik side has ip 10.0.3.2, Pfsense – 10.0.3.1.

I have routes:

Destination Gateway Flags Netif Expire
default 10.20.117.193 UGS vtnet0
10.0.3.0/24 10.0.3.2 UGS ovpns1
10.0.3.1 link#6 UHS lo0
10.0.3.2 link#6 UH ovpns1
10.20.117.192/27 link#1 U vtnet0
10.20.117.194 link#1 UHS lo0
127.0.0.1 link#2 UH lo0
192.168.23.0/24 10.0.3.2 UGS ovpns1

I can ping 10.0.3.2 (Mikrotik) from Pfsense.
A can ping 10.0.3.1 (Pfsense) from Mikrotik.

But, if I ping 192.168.23.1 (Mikrotik side additional IP) from Pfsense I can’t see any tcpdump on Mikrotik side. It’s like Pfsense don’t send any packets to Mikrotik.
