Connecting to a Client behind a RRAS and a Router:

Question

My setup:
(ip numbers are examples, not real configs)
Router:
IP 192.168.1.1
Mask 255.255.255.0
Gateway 192.168.1.1
DNS: Provided by ISP
RRAS 2012 R2 NIC1
IP: 192.168.1.2
Mask: 255.255.255.0
Gateway: 192.168.1.1
DNS: 192.168.1.1
RRAS 2012 R2 NIC2
IP 10.1.1.10
Mask 255.0.0.0
Gateway: none
DNS 127.0.0.1
So everything works fine but lets say i have a client that has de ip 10.1.1.15 and i need to RD that one. I know that this might be a stupid question but how do i route a remote desktop through two different networks?

Answer 1

I am unable to connect from an external. Connecting to the RDS Server ( I said client, i know, sorry) with a client PC works fine. The tutorial you posted is the one i used to install the RRAS role and it works fine as intended (internet connection for the
users).
So, how do i connect from my home PC to the RDS server? I tried to use a random port (2212), which i forwarded like this:
From: All external IP's
To: 192.168.2.4 (static RDS server ip)
External port: 2212
Destination port: 3389
This did not work, probably because the Router ip is 192.168.1.x with a 24 bit subnet mask.
Then i tried this:
From: All external IP's
To: 192.168.1.49 (public NIC of the server that has the RRAS role installed)
External port: 2212
Destination port: 2212
On the RRAS server i forwarded the request, in the Advanced Firewall settings, from port 2212 to port 3389 and added the ip number of the RDS server as the destination IP. I have not changed anything on the RDS server, since RDP is open on all network types.
I am probably way off from the solution for getting this to work properly.
