Why can't I see the network behind the openvpn server?

Question

openvpn

Raised at the central office on windows server 2012 (192.168.2.100) openvpn, in the branch, the openvpn client is configured for Mikrotik, the connection goes through at vpn 10.8.

How can I generally configure that the branch PC would see the server at 192.168.2.100, and the rest of the center PCs would be unavailable? And at the same time, the server saw all the computers in the branch?

ccd:
push "route 192.168.3.0 255.255.255.0"

Answer 1

I would venture to suggest that the leapfrog with routes
instead of push "route 192.168.2.0 255.255.255.0" draw
route 10.8.0.0 255.255.255.0
ccd there should be an address that you can "see"
push "route 192.168.2.100 255.255.255.0"
you can also have a dns address push if available
push "dhcp-option DNS 192.168.2.100"
service restart
