Is the VPN Client not visible from the Server's network?

Question

VPN

Good time!
HELP broke the whole turnip... in networks, apparently, I'm very bad...
There is a Mikrotik VPN l2tp server.
(shortly - the vpn pool is in the same subnet as the rest of the devices, on the proxy-arp bridge)

The client is connected (Windows 10) and from the client side everything is good in any case, there is access to the network and all its devices, but here is access from the network to the VPN client is possible only when the checkbox "use the default gateway on the remote network" is checked on the client, which is very bad in terms of traffic.

A client with a dynamic external behind nat, subnets are different, but both are class C (192.168.x.0)

It seems to me that I'm stupid in setting up the client part, but if necessary, I'll pull out a print of the router config.

PS: Bliiiin .... in short, I grabbed a working laptop and drove in the VPN connection settings - successfully!
And pings to the client go, and IPsec has risen .... in short, a week of hassle because of the blind faith that there can be no problems with your combat home PC ...

Thank you all for your participation !!! it’s a pity that he dug in the wrong direction, so he also strained others ...

Answer 1

On clients, one way or another, you need to prescribe a route to network resources through vpn.
As an example:
The resources of the remote network are in the subnet 192.168.0.0/24
The vpn endpoint from the server side has the address 192.168.1.1
The vpn endpoint from the client side has the address 192.168.1.x/32
You need one way or another show the client the route to 192.168.0.0/24 via 192.168.1.1. Please note that if the client's home network is also 192.168.0.0/24 - one way or another there will be problems, even if something partially works.
