[App_rpt-users] iPhone Verizon Hot Spot Issues

Wed Nov 15 21:34:41 UTC 2017

Thanks David,

Hmm, interesting. I’m leaving in about 30 minutes so I’ll connect it now. Good idea and thanks…

And upon further inspection of my LTE connection to my iPhone, it has an LTE IP gateway of 100.100.x.x, which tells me CGN (Carrier Grade NAT) is being used. So yup, double NAT since my phone also hands out a private address. This is common practice since the exhaustion of IPv4 addresses.

More about CGN if you aren’t familiar:

I will go ahead and connect up my hotspot and give it a shot. Thanks all…

The Hotspot gets an IP address and then ASL needs to update the node list server. Then the clients needs to update the nodes list. So this can take sometime. So it can take around 30 minutes or so. For testing, let your hotspot ASL node run about an hour. Then see if you can connect.

Outbound doesn't need the ports open.

Thanks Carl,

Yes, I am using my hot spot for a portable allstar node. I understand that with Verizon port forwarding is impossible without the one-time $500 static IP, however port forwarding shouldn’t be required for outbound only connections. It’s odd, I can attempt to connect to a node and it never connects, then 5 minutes later I can try again, and it does connect. Or I may try node AAAAA and it doesn’t connect, then BBBBB and it connects, then AAAAA and it doesn’t connect. But others can connect to AAAAA. Or when I get to work or home on WiFi then I can connect to AAAAA. Then 10 minutes later I leave the house and I connect to AAAAA just fine. In other words, there is no logical pattern lol.

I guess I need to start writing down what nodes and can and can’t connect to, and when. And start watching the Asterisk CLI to tell me what’s going on. I’m a network engineer working for an Internet service provider, so I can troubleshoot, but I haven’t began troubleshooting yet. I was just probing the community beforehand which could save me some time in the long run. I figured (hoping) someone have had to run into this before with all the portable nodes already out there.

Are you trying to use your phone as a hot spot for the Asterisk device?  If so, you will run into issues with port access. All of the major carriers (Verizon, AT&T, Sprint, T-Mobile) have laid out there LTE networks in a manner that result in dual-NATing, there is no way to port forward from the “real” internet address to a device connected to your hotspot.  Verizon will give you a static IP with ports available for a mere one-time fee of $500. I don’t know what other carriers want.

Hi All,

Anyone use their iPhone hot spot on Verizon? Any issues? Mine gives me a fit not wanting to connect to most any node (mine and others) most of the time. After constantly rebooting my node and phone several times, and retrying to connect to various nodes, sometimes it’s eventually successful.

Any similar experiences? Suggestions?
