Dear,
For learning I created my own domain at my home. This is working properly as I can remote desktop from any place to my home.
The only problem that I have now is that my rras server won't allow any rdp sessions.
If I want to take over remote my Domain controller now,I need to remote first to my 1st software firewall ( which is normal )
then I need to take over my second software firewall and at last I can take over remote my domain controller.
For that reason , I've added a rras server to my network ( red part ).
I installed the roles, configured routing and remote access as ( custom -> LAN ) according the microsoft library:

When I try to ping the 172.16.x.x network from 192.168.1.x I receive nothing. When I try to ping 192.168.1.x from 172.16.x.x this works fine ( this always worked, even without the RRAS server ).
As for troubleshooting I turned of the firewall completely on all machines and still do not receive any ping-packages / rdp-packages.
How my network looks like :
What am I doing wrong ?
