Hi Britgirl

I sent you the file(s) by email (using Reply To) on 26 June, trust that was ok(?).

Hi, has my last post fallen through the cracks, or am I impatient?

I look forward to receiving a debug version of the library to gather more information to help investigate why public IP publishing is not working on a Windows 7 PC.

Would you be willing to help and test it for us?

Yes, thank you

Using corrected syntax  nxupnp.exe -A list 4000 -R 4000 TCP 600  I get:

Added port: 4000

Local IP:  192.168.1.3

Gateway IP:  192.168.1.1

External IP:  121.xxx.xxx.xxx

If we use this 121.xxx.xxx.xxx IP and 4000 Port combination, connection is made, ie  it works.  Great.

However, when starting NoMachine by clicking on the Windows Desktop icon, only an internal IP is displayed (192.168.1.3).  No external IP and Port is displayed.  This is the same problem referred to in my first post.

Is there a reason NoMachine failed to add Ports and give an External IP?  Is there a way to do this manually?

I downloaded the binary file, thank you.  Looking in  C:\”Program Files (x86)\NoMachine\bin” there is no nxupnp.exe file.  To make sure, I uninstalled NoMachine, downloaded the latest version and installed.  Again, inspecting  C:\”Program Files (x86)\NoMachine\bin” there was no nxupnp.exe file.  Never the less, I copied the file you provided and copied it to C:\”Program Files (x86)\NoMachine\bin” as nxupnp.exe (Windows did not complain saying there was another file of the same name).  Running nxupnp.exe -l gave no output.  Running nxupnp.exe -v reported Port forwarding protocol: ‘auto’

Using the known external IP address to :  nxupnp.exe -A list 4000 -R 121.xxx.xxx.xxx TCP 600 

Failed to add ports

Local IP:  192.168.1.3

Gateway IP:  192.168.1.1

External IP:  0.0.0.0

Thank you again.  Checked all those.  The Win 7 PC configuration is the same as a Linux Mint PC setup (on the same home network) which announces an IP and a 2xxxx Port to use over the internet.  TWin 7 PC does give an IP and 2xxxx Port to use over the internet.  Checking on ‘Gateway port’ provides a port, but using that port with my known internet IP does not enable/permit connection from a remote PC.

Thank you Britgirl for your reply.  I don’t have this problem with Linux computers on the network/modem, they provide an nx IP address and Port that can be accessed from other computers outside my network.  So I feel the modem can be ignored as the cause.  The problem therefore must be within the Windows 7 computer setup.  I previously used Hamachi on the Win 7 machine, and when NoMachine started, it produced a 192.168.1.8 address and a Hamachi address, but not an nx address.  I uninstalled Hamachi and all its data, so now I get only the local address (nx://192.168.1.8).  Any ideas?
