Access to NoMachine server from outside local network

[oliv30]

Hello

I have an internet box (live box orange) connected to an Asus router with DHCP enabled on it.

On my NoMachine server I can see IP of my router Asus (192.198….) but no access from outside. I believe that I must forward something else?

Could you help me

Hi Oliv30,
it seems your router is behind double NAT.  To connect from outside the local network, you need a public IP address. What operating system are you using?

If it’s Windows, search for and run cmd (command line)
. In it, enter the command tracert 8.8.4.4
The command shows which routers your packets go through.

The results should look similar to this
:
1     2 ms     1 ms    <1 ms  routername.x.com [192.168.1]
2    62 ms     2 ms     1 ms  some name   [second IP address]
…
…
9   *   6 ms  6 ms    dns.google [8.8.4.4]

On Linux in the console you can use a similar command traceroute 8.8.4.4
You may need to install traceroute
 command..
The results will look similar to Windows

.
If the second IP in the results is an address for private networks, e.g.
A 10. 0.0.0 – 10.255.255.255
B 172. 16.0.0 – 172. 31.255.255
C 192.168.0.0 – 192.168.255.255

This will mean that your router is behind double NAT.

Tom

P.s the upcoming NoMachine Network feature of version 9 will solve all these networking problems. There will be no need to know your computer’s IP address, or other network details. Publish your computer on NoMachine Network, log in to NoMachine Network with your NoMachine account and connect. See this page for more info: https://www.nomachine.com/network
