Port Forwarded not working, exahausted possible solutions

[French Fry]

Running Vagrant 1.95 with VirtualBox Version 5.1.22 r115126 (Qt5.6.2).  Box is bento/ubuntu-16.04. Host is Windows 8. 

ssh is working so no problem there.  What I can't do is either telnet or connect through host browser. Here is the relevant section of the Vagrantfile

config.vm.network "forwarded_port", guest: 1125, host: 4567, protocol: "tcp", auto_correct: true
  config.vm.network "forwarded_port", guest: 1125, host: 4567, protocol: "udp", auto_correct: true

I added the protocol and auto_correct options recently but they haven't changed anything. 
Also enabled Vagrant logging and am not seeing any issues regarding the ports.   Running
sudo netstat -lptn and other options shows the ports of ssh and my postgresql listening, but nothing for the forwarded ports in the config file. 

I was able to netcat the port,  that worked for telnet.  No firewall running on Ubuntu (ufw status - inactive) and iptables is basically empty / no rules defined.  Not that it would matter with ufw off.

I've also done multiple tests with Windows firewall off, so the problem doesn't appear to be there. Checked my router and still no issues (not running a firewall on the router). 

Googling around there were some suggestions to use a bridged connection in Virtualbox as opposed to NAT, though if ssh is working, why wouldn't telnet and ultimately my browser. 

Looking for some suggestions / help on this issue.  Thank you!

One thing you can do: While the VM is running, you can play around with port forwarding, live, from the Network configuration section of the VirtualBox GUI (the first interface--the NAT one: Advanced > Port Forwarding). That way, you'll know if you're dealing with a Vagrant or VirtualBox issue.

can you share:

output of:

vagrant ssh-config

and from the guest

sudo netstat -anp | grep 1125

On the windows, open one powershell session, not sure available on windows 8 but try:

tnc localhost -p 4567

share output

Thanks

I ran the tnc on the port in Windows Powershell but couldn't figure out the command to write to file.  It did not make a connection though and exited.

So on the guest, what service is the one that will get the traffic coming to port 1125 ?

Probably none :)..  This is being set up for Rails dev, so I want to access the app with the host browser.  I know Puma is running the app, and that is probably a different port but wanted to get the port forwarded down first before moving on.

If there is nothing running on the port then nonthing will show up in the browser.

in the netstat you did share was nothing there.

So, lets say you start an up on port 8080 on the guest and you make the port fwd from 8181 in the host.

if you do on the guest netstat -anp | grep 8080 you should see something doing the listening

if the app is browser then you can test on the guest like

curl -L http://localhost:8080

Then on the host:

you can test the port is reachable with . tnc localhost -p 8181

then on the browser in the computer try  http://localhost:8181

However,

If you add a private_network, and assign an IP like 192.168.56.21 then all gets easier

since on the guest you can do

curl -L http://192.168.56.21:8080

and ont he host you can also use the same url

I'll probably work toward setting up a private network.  What about telnet though? telenetd exists but perhaps I need to configure it. 
Thanks for the help, greatly appreciated.
