Can I tunnel thru my Verizon cel phone?

Here's the hardware:
Verizon LG G6 supplies a hot spot which is connected to by a TP-Link Nano router which is cabled to the Wan port on a MikroTik hAP ac lite.

My computer is plugged into the Mikrotik, and i'm surfing the web just fine.

I set up a tunnel from my existing tunnel server node and it's similar to other tunnels i'm serving.
On the client i'm using my kg4ikt.ddns.net like other clients that connect to my server.
Doesn't appear to make a connection.

Is this a port 5525 issue?


I looked at the data from the client node and found this;
Tue Jan 29 21:12:30 2019 daemon.info vtund[3494]: Connecting to kg4ikt.ddns.net
Tue Jan 29 21:12:31 2019 daemon.info vtund[3494]: Connection denied by kg4ikt.ddns.net
Is there a connection limit to ddns.net?

looks like a password or hostname issue.   Check the server log side to see if there is a logread entry for failed login.    To diagnose network connection issues, on the client  side, "telnet <IP of tunnel server> 5525"    If it connects and you see a vtun header line, then the network is correctly configured and not the problem.

The "telnet <IP of tunnel

The "telnet <IP of tunnel server> 5525 " does connect.

Below is some of the data file.
How about that "bad address at /var/run/hosts_olsr line 2"? See my notes further below.

Should I be concerned about all the denied connections?
My cel currently has 174.195.129.56

'How about that "bad address at /var/run/hosts_olsr line 2"?'
line 2 is a comment line that dnsmasq doesn't expect.  It does no harm.

'The entry 10.76.213.112 is for that nodes' RF which is turned off."

When the nodes' RF is turned off (interface is typically wlan0), then another sudo interface is defined instead, which is up and live.   It is still a valid routable IP address, and the primary address used on the mesh, to route to this node.

looks like a password

looks like a password mismatch.  Doublecheck the password entries on the tunnel server and client to ensure a match.  Make sure that the server has the connections enabled.

passwords are fine, same one

passwords are fine, same one i use for the other existing tunnels on my server.

After issuing the "telnet ip 5525", are there other commands i might issue?

Interesting.   Can you copy

Interesting.   Can you copy the following file from both the tunnel server and the tunnel client (/etc/config/vtun) and email it to me at k5dlq@arednmesh.org?
DO NOT POST IT HERE as it contains sensitive information!

I'll take a look and see if I can determine what's going on with the issue.

Thanks,

Can't connect to same Tunnel Domain

Not sure if it applies in this case, but I have found that I cannot connect to my domain from within my domain - if that makes any sense.  If you are using the Microtik as a "client" that is connected to your Cellphone which is supplying the internet connection - that "should" work.  Just make sure that there isn't a connection to your Wi-Fi or anything that looks like a connection to your local network from the tunnel client that is attempting to connect.  What happens if you try to connect to an external Tunnel server?

Make sure the hostname of the

Make sure the hostname of the tunnel client is identical to the hostname the server knows it as.   As I recall, both the hostname and the password need to be exact, like user and password login.  Since we can do a telnet client->server, we know the network is ruled out.

The solution - (for now)

Working with Jeff on this - we reduced the Tunnel Client Node name from 28 characters to 24 characters.  This took care of the issue, so there still seems to be problems with long tunnel client node names for connection to a tunnel server.  I had once thought the limit was around 31 characters, but I never really experimented with it to see "where" the cutoff was.  Maybe someone else can shed some light on this matter.
