How to configure VPN client access from another subnet to the office subnet?

Question

Mikrotik

Good afternoon! The task is to move VPN (L2TP) clients to a separate pool of addresses on Mikrotik. The addressing is as follows:
Office - 192.168.88.0 \24
VPN Clients - 192.168.1.0 \24
And everything seems to be fine, I was able to connect from the client, on it I registered the route to the network 192.168.88.0 \24 -ping went to 192.168.88.0 and 192.168 .1.1 (VPN gateway), a route to the client is also created on Mikrotik - accordingly, there is a ping. But there is no access from the client to the resources of the office network (balls, other PCs, etc.). Question - why? After all routes to subnets are registered.

Answer 1

Need to NAT. Or register a return route on the balls, other PCs. By the way, what are the IPs of the balls and other PCs? They are also at 192.168.88.0/24 if so, then it may well be necessary to configure a firewall there.
