How to make 2 network cards see each other?

Question

Computer networks

The situation is the following. On the server 2 setevukha.
One is connected to the router and looks at the Internet, its local IP: 192.168.88.10.
The second network card looks into the LAN and its IP: 192.168.0.1. It has DHCP enabled.
RRAS is configured so that local network clients receive the Internet. Everything works correctly.
But at the same time, ping only works in one direction. 192.168.0.1 pings 192.168.88.10 from 192.168.0.1, but not vice versa.
Tried to register static routes in RRAS, but nothing has changed, or wrong routes.
Tell me what can be done?

Answer 1

Nothing to do, that's how NAT works.

Answer 2

Start with
route print
Explain to the heap where the ping comes from, because in theory everything should be fine on one host?
Means at least 3 hosts.
In theory, you have a Mikrotik router, why do you need RRAS?
