I hope someone can help me.
I think this might be a relatively easy answer but I am struggling to get this to work properly.
I have configured an IPSec VPN connection which the clients connect to.
When connected, they receive an IP Address of 192.168.6.x/24.
Once they receive this IP address they can then connect to any server on our 192.168.1.x/24 network via any service.
I now want to restrict all users connecting as 192.168.6.x/24 to be restricted to only being able to access 192.168.1.17 on port 3389.
