Cannot Connect to RailPro Server
William Brillinger:
Ken, do please also make sure Ring knows that you are having the CGNAT issue.

I will let Ring know there is another user behind CGNAT!
as expected, I can't reach the server from Rail Pro Assistant.
I also cannot connect to the server when I use my iPhone's hotspot (Verizon) connected to my PC. is that user error or is that not expected to work, either?
how do I test for CGNAT when connected: PC-->hotspot-->internet?
thanks!
update: I stopped at Starbucks and verified that I can connect to the Ring server using their wifi, so that (or doing from my church's wifi) will be the work-around.

This. Telco's use CGNAT virtually exclusively. If you imagine Verzion had 1 million mobile data customers and each of those customers had at least 2 devices (say phone + iPad) that'd be 2 million public IP address they have to have on hand (at about USD$20.00 a pop these days). That's not going to happen so they use CGNAT for mobile data connections.

You can use the UDP test tool found here in the files section to do a PAT test. That's probably the easiest way.

Tim--at the risk of causing thread drift, in a nutshell why don't isp's want to convert to ipv6? I assume there must be costs involved?
G8B4Life:
Simple. It costs money to deploy and test it. CGNAT is much easier to implement and costs less (short term thinking). CGNAT was really only supposed to be an interim for ISP's, backbone providers etc while they deployed IPv6 but generally speaking many are taking "interim" to the extreme. The number of ISP's here using can be counted on one hand, with missing fingers!
