Hello,
I have been trying to setup up some nat rules to be able to RDP from one subnet to another.
Here is my setup.
My office is on a 192.168.1.0/24 network on ETH4 of our RB1200
I have a ubnt air router in our techroom that is set in SOHO mode. It has a static IP set to 192.168.1.121 on the WAN and I have DHCP setup on its LAN to hand out 192.168.253.2/24 range. I have a Static IP on the Machine I want to RDP to and allow it to access the 1.1/24 network. Static of 192.168.253.167
How do I make my rules to be able to access the 192.168.253.167 via RDP and to let 192.168.253.167 access my 1.1/24 network?
You will need to have route in each router pointing to the other subnet.
Hm… he runs the AirRouter in SOHO mode (NAT), so this won’t work. If he would route it, you were right.
192.168.253.167 should already be able to access 192.168.1.0/24 since you are running the AirRouter in SOHO mode. It’s just like 192.168.1.0/24 were the Internet and 192.168.253.0/24 would be your LAN.
What you need to do is to configure the AirRouter so it will forward TCP port 3389 (RDP) to 192.168.253.167. This way you could reach your Machine over the IP 192.168.1.121 and your RB1200 doesn’t care because it will never know about 192.168.253.0/24.
We had set it up like you said Mat. For some reason it was just not working. So we went through the AirRouter and re-applied the settings several times for port 3389 and it finally worked. Not impressed with the AirRouters at all.
