My modem is Hitron CGNM-2250, and I want to be able to have the remote desktop connection working within the LAN. All of my LAN's RDC was working before I switched to the Hitron Modem. Any idea?
shaw-brayden, that doesn't make sense for LAN traffic.
robertlo Are your computer's IP address assigned statically or dynamically? Either static reservations in the router or true static IPs on your computers?
My first thought is that the internal IP addresses have changed, and/or your computer firewalls have changed to 'Public' network locations and so blocking access.
Which OSs are you using?
Hey there robertlo,
Thanks for reaching out! It's likely that your remote desktop connection is not working properly due to the router's built in security that is blocking it as potentially dangerous traffic. In order for this to work, you'll have to open up the port(s) and computer's IP address that you want to run remote desktop on.
What program are you using to do remote desktop? The port number that you need to open up depends on the program/way that you're remoting in to your computer. If you are using the built in remote desktop application in Windows, I believe the port for that is 3389 and uses TCP.
In order to set up port forwarding for this, you'd need to log in to your router by going to http://192.168.0.1 where you would enter in the router's username + password (located on a sticker on the side of the unit), then hit Login. After you have logged in, click on Basic at the top of the page, then click on Port Forwarding.
Once you are in the Port Forwarding Options screen, you can set up a rule to allow access to a certain IP on your network (the computer you're wanting to set up port forwarding to) on a certain port. Click on Add Rule and fill in the IP address of the specific computer, set it to TCP and then Save Changes.
If you're not sure what the IP address of your computer is, you can find it by following the instructions here.
Hope this helps! And please note, port forwarding is not something that is officially supported by Shaw, but we wanted to point you in the right direction.
EDIT: The above information is for if you want to RDA in from over the internet, I misunderstood your question. Sorry for the confusion!
Kevinds, you are correct, the outbound/inbound port forwarding setting shall not affect LAN traffic. Both of my LAN's remote PC have static IP address. Finally, I hooked up the monitor to both PCs and found out the firewall is on (WIndows must change the setting because of the new router). After changed the firewalls settings, both RDC connections are working now. Thanks for helping me
The OS of both remote PC's is Win 7.
When using a laptop for example, when you connect to a random network there is a pop-up "Is this network Home Work or Public" (something along those lines)..
Each having their own automatic firewall rules. No answer means public, so the firewall turns back to 'high'.
If you edit the firewall rules, you can allow remote desktop in all three zones, then it won't happen again.
