Default Gateway address for multiple VPN users/clients

Question

Hello,
We need some help with a VPN setup for a school project.
What we want to do:
We would like to have aprox. 10 different VPN uses that can connect to our Windows Server 2012 R2 which is setup as a VPN server, by the Role called Remote access. And the VPN server is working and we are able to connect to it from another location/computer.
Our current setup:
We have a Cisco router, that are configured with 10 Vlans, from Vlan 10 to Vlan 20, and a managament Vlan called Vlan 100.
The Cisco router is also acting as DHCP server, so inside each Vlan the DHCP gives IP addresses to that specific Vlan, Ex: Vlan 10 has a 192.168.10.0/24 network. Vlan 11 has a 192.168.11.0/24 network, and so on. Vlan 100 has 192.168.100.0/24 This Vlan 100
has connection to all the Vlans.
We have internet connection on the Router on port 0 and each Vlan are connected to the internet.
We have setup the VPN server with a static IP configuration so it is inside Vlan 100 with a Default gateway, like 192.168.100.1 So the VPN server is connected to the internet.
In AD we have created a User and assigned a static IP address in the user properties, under the Dial-In tab. Here we give this user this IP 192.168.10.225
Now when we connect to the VPN server useing this user, we have no connection to any of the Vlans (ping) and no internet. When we in cmd write ipconfig we can see that our VPN connection has this IP 192.168.10.225 but a Subnet called 255.255.255.255 and
a Default gateway called 0.0.0.0
We would like the user to recieve the correct IP settings like: If we connect with our user, it should recieve the IP as it does, but also a subnet called 255.255.255.0 and a default gateway called 192.168.10.1
How is this achieved?
The reason we want this is: We want to create a VPN user for each Vlan. So a user with permission to access Vlan 10 but are not able to see the other Vlans, and then a new user to access Vlan 11 but not able to see the other vlans, and so on.
Hope someone is able to help us to understand how this is done.
Thank you in advance.

Hi,
In brief, we can't achieve this. Normally, we would not do this.
Usually, we use firewall or ACL to restrict the remote users.
For example, 192.168.10.100 is assigned to user1 and 192.168.10.101 is assigned to user2. We can use firewall to restrict 192.168.10.100 to access 192.168.10.0/24 and 192.168.10.101 to access 192.168.11.0/24.
