On your network, which machine is responsible for updating X. whenever your ISP-assigned public IP address changes? Some routers support it directly on the router itself.Is there anything else I should check to narrow down the issue? # LOCAL NETWORKįor scenario 2, it looks like this. Could this be an issue? I'm not sure if this answers your WAN question, but I observe the following in both scenarios. I am connecting my Linksys WRT3200ACM to an Xfinity Gateway (Arris TG3482G), and doing my work on the Linksys router. Within my network and from outside my network, nslookup gives the same result for scenario 1 (where DDNS points to private IP) and scenario 2 (where DDNS points to public IP). Port forwarding does not work in setup 2.Įxample Router Port Forward Config: Application Name External Port Internal port To IP address Protocol This partially works for setup 1 (described above), but only locally. I enable port forwarding for my Device IP (.X for NoMachine), from port Y to port Y. However, I am not able to port forward through this port even with my firewall and filters turned off.įor port forwarding, I go to my router settings at 192.168.1.1. This uses a public IP (73.174.X.X) and therefore can be accessed locally and from outside my network.
Scenario 2: I can have my Ubuntu system update X. I can port forward locally but not from outside my network. Though this works locally, the IP pointed to is private (being 10.0.X.X) and therefore is not accessible outside on the network. Scenario 1: I can have the router be responsible for updating X. I am able to realize two possible scenarios: In this edit I try to respond to the questions asked and clarify my language based on my reading of the issue and some updates. The feedback so far has been really helpful. How do I find the Device IP I am supposed to use to enable port forwarding over my Dynamic DNS? It also seems to think 10.0.X.X should be the IP used for port forwarding. The Dynamic DNS provider provides a tool to check if port forwarding is enabled. However, 10.0.X.X is not the correct form and it says 192.168.1.1 is an invalid IP.
The router expects a Device IP of the form .X. I am able to ping X. from inside my network but not from outside. This also happens to look identical to if I went to 192.168.1.1 (the router login page). When I do nslookup X., I see the url directs to address 10.0.X.X. I have setup a Dynamic DNS through my router with url X. I am trying to enable the ability to connect to my router from outside my network through a Dynamic DNS and I am stuck on port forwarding.
