Pure fiber- looks like public IP, but is unreachable outside Telus

I’ve got Telus PureFibre 1.5/.95 service in North Vancouver.

 

The Nokia fiber device is plugged straight into an Eero. The Eero gets what looks like a public IP address (173.180.26.88). All the devices on the internal network are 192.168.7.x

To avoid any port blocking, I’ve got the Eero set to forward port 65001 -> 22 on my Mac for ssh. 

 

If I’m on another device on the local network, I can ssh to [email protected]:65001 successfully. However, as soon as switch to another connection (via a VPN, or via a Bell LTE connection) the connection reliably fails. 

 

My first question is: Is my apparently public IP address actually behind some sort of grotesque CGNAT? 

 

Any ideas on what’s wrong / how to fix?

  • I can ping your external IP so it is indeed public. Perhaps you have some firewall rules blocking access on the Eero?

      Yeah, I’m beginning to think that the Eero is behind this, and of course its beautifully simple app doesn’t have any logs to view or anything helpful in this regard.

      There’s no apparent firewall running on the Eero, so I’m going to ping Eero support and see if they’ve got thoughts.

      Thanks very much for the help!

        Np, let us know if you get this resolved. Port forwarding issues come up often here so it would be beneficial to all.

         

        I know it works because I set up external access with port forwarding to my security camera DVR many years ago and it's still working.

  • What does canyouseeme.org show you for your public IP address?

      Everything (canyouseeme, whatismyip, speedtest, etc.) shows my WAN IP address (173.180.26.88),

        Then you are not behind carrier grade NAT. The issue narrows down to port forwarding. Does port 65001 look to be alive from canyouseeme.org?
