Mikrotik + Kerio how to do reverse routing?

Question

network hardware

When switching to another provider, I had to put Mikrotik on the border.
The bottom line is, we have a Mikrotik acting as a gateway (4.4.4.1) for kerio (192.168.1.10), with a WAN port of 9.9.9.9
There is a pool of white ip addresses 4.4.4.0/27
Going online through kerio, I see myself as 4.4. 4.10 (internet interface on kerio)
But, if I am a person from the outside, then I cannot reach the address 4.4.4.11. No reverse routing.
In Kerio, everything is set up correctly, because if, conditionally, you remove Mikrotik and get a gateway from the provider, everything will work

Answer 1

Knight's move - do it as a provider - route the resulting subnet to Kerio.
