I've been trying to configure forwarded ports for various services (VPN, ssh, HTTP, etc) and have been unsuccessful. While diagnosing the issue, it appears my Google Nest Wifi router (Model H2D, Software version 14150.43.81) is not properly forwarding ports. Here are the steps I used to reproduce the error:
All of this indicates to me that local connections work fine, but remote connections, even though the client believes it's working, are not getting to the forwarded host inside my network. I've tried this with multiple ports and using TCP only, UDP only, and TCP & UDP and none work.
Is there an update I can apply, or a configuration setting to tweak to get this to work? I would very much like to get this up and running. I know it worked previously (having had this set up ~1-2 years ago) using the same configuration steps, so it is perplexing why it does not work now.
Try a reboot/ power cycle. Worst case try to factory reset and set up from scratch.
I struggled too when port forwarding for Plex, but after some reboots, waiting, testing it suddenly worked.
Other things to check:
Maybe you can find other things to check from previous threads on this topic:
I'll see about doing a reboot/power cycle, but it'll have to wait until the weekend (as I work from home and doing a reboot mid-week would be disruptive; a factory reset quadrupley so). For the other suggestions...
And thanks for the LMTGFY link. Found it amusing that this thread was the third link I saw 🙂 Looked through the first four pages of results and none of the pages that were similar to my issue had any new advice, though one did have a link to https://www.portchecktool.com/ which reports no services listening at my IP on the ports I'm testing, so it's not just my testing with nc that's failing.
After a lightning strike, a replaced cable modem, and a complete reset of the routers it appears I am getting some port forwarding with Plex (which was one of the apps I was previously having issues with). I've not re-tried setting up the VPN due to lack of time. When I can get back to it, if I have additional issues I'll post on a separate thread. But for now, I'm closing this one since, while I don't know which of the many changes I did sorted the issue, it has been sorted.
Thanks for visiting the Community.
Glad to know that this has been sorted. I'll consider this post as complete and will lock the thread in 24 hours. Feel free to start a new thread if you need assistance with your Google Nest Wi-Fi devices.
