Port Forwarding - Two Routers and RDP

Hello All,

 My goal is to segregate a separate domain and domain controller from the production in house network. I need to provide the separate domain with internet access. I also need to allow for RDP on a separate port (this has been configured on server, and firewall rule changed on server).

 On the HP I have setup another VLAN (2) and tagged it as participating in VLAN 2. I have also untagged the port in VLAN 1.

 IP Ranges in house;

 Production network: 192.168.1.X
 Gateway: (Router 1) 192.168.1.254

2nd Network RV042 Router 2: 192.168.1.24 (external- gets IP from 1.x range) / 192.168.10.1 (Internal)
 Separate DC: 192.168.10.2

The separate DC is not allowed to see any other PCs or servers on the network, which is why I am using a second router. It will be used as a hosted terminal server for a different business entity.

I am trying to pass RDP through on a different port (4000). I opened the port 4000 on R1, and pointed it to R2. I then opened the port on R2 and pointed it to the DC sitting on 192.168.10.2.

For some reason, it still isn't passing through. When I use canyouseeme.org to test the port, it shows it as closed.

Thanks in advance for the help!

Are you translating prot 4000 to port 3389 on router 2?

Commented:
No, since I did a registry change on the server to accept RDP on port 4000 instead of 3389.

does it work on the local subnet?

Where will you be RDP'ing from? outside the network or internally or both?  Are you specifying the port you are trying to connect to when doing RDP?

computer ip:port ..... for example..... 192.168.1.1:4000

Points for effort.

The problem ended up being wrong port forwarding rules on the router. I must have fat fingered typed them in.

Both of the troubleshooting steps you guys provided pointed me in the right direction.

Thanks.
