Hello, welcome to NETVN channel
In this video I show you how to monitor devices over the internet with PRTG
In fact, there are network devices that are separated by firewalls, separated by the internet, but you still want to monitor it
So how to monitor such devices
PRTG will give you the solution to that problem
In this example I will install PRTG Core on a computer running Windows 11
Then I will install remote PRTG on another computer running Windows 10 that is separated from Windows 11 by the internet
The Windows 10 computer will connect to the PRTG Core and will send the sensors it monitors network devices to the Windows 11 computer.
That way you can monitor network devices, remote servers over the internet
I have finished installing PRTG core on my computer running Windows 11
And here are the necessary settings to allow the PRTG remote to connect to it
First you change the default password of PRTG Core
Default password after installation is prtgadmin
I will set a new password, I recommend you set a strong enough password to protect your network monitoring system
I have finished creating a new password for PRTG Core
You set the time zone to suit where you live
The correct time zone will tell you the exact time of the problem
Since I allow access to the PRTG monitoring system from outside the internet, I will enable https
This helps encrypt packets when sending over the internet environment and prevents bad guys from stealing your information
To apply https activation the PRTG core monitoring system will reboot
It will ask to re-login the monitoring system
By default, PRTG Core only allows access from within the local network so I will set it to allow access to this system from anywhere
Just like last time this setup requires a system reboot
And once again I was asked to log in to the monitoring system
My monitoring system automatically discovers and monitors the sensors of the network devices it discovers
As you can see, there are some danger warnings for some of the devices it discovers
Next I will set up this monitoring system to be accessible from anywhere
To do that, I set up port forwarding on the router
Before forwarding the port on the router, I set up a static ip address for the computer with PRTG core installed
If the ip address of the Windows 11 computer changes, the port forwarding on the router will fail
And then you can't access the network monitoring system from the internet
Here I set the static ip address for Windows 11 computer to 10.11.32.216
You set up a static ip address for the computer that installs PRTG core in accordance with your network
Now I forward the ports on the router
here are all 3 port forwarding settings on the router
I forward port 80 to ip address 10.11.32.216 so you can access the system by http
Next I forward port 443 to ip address 10.11.32.216 so I can access PRTG network monitoring system using https
As set up in the previous step, I use https to secure the network monitoring system from bad guys
The last port to forward is port 23560, it helps PRTG remotes connect to PRTG core
For each type of router, there will be different port forwarding methods, but the ports to be forwarded are the same
If the ports to be forwarded like 80 or 443 are already in use, you should change to another port to suit your network.
And here are the port forwarding settings on my router
Now I want to know my public ip address so I go to ping.eu
And here is my public ip address 14,226.91.53
I will access the PRTG monitoring system with a public ip address
But by default the Windows firewall will prevent you from doing that so you set it to be allowed to go through the Windows 11 firewall.
I also need to allow port 23560 to pass through my Windows computer's firewall
So I will set up on Windows 11 firewall as follows
I created a new rule to allow port 23560 to pass through the firewall
Port 23560 allows PRTG remotes to connect to the PRTG core and send the monitoring information it collects
I set up a new rule on the firewall and allowed port 23560 through
You give it a name you like
So I have completed the setup to allow port 23560 to pass through the firewall of the computer running Windows 11
I open any web browser and enter the public ip address to access the PRTG monitoring system
I was asked to enter my username and password
That way I can access the PRTG monitoring system using the public ip address
So I finished the setup on PRTG core and completed port forwarding on the router
And I also need to allow ports to go through Windows firewall
Now from a Windows 10 computer I will connect to PRTG core over the internet and send the monitoring results collected by this computer
First I connect to PRTG core from Windows 10 computer
I open any web browser access PRTG core monitoring system with public ip address
As you can see the public ip address of the Windows 10 computer is different from the public ip address of the Windows 11 computer
Thus the two computers are separated by the internet
Next I set up to connect to PRTG core as follows
From the menu bar select Setup then Core and Probe
Next you add a new probe
Then you download the installer and install it
It will take a while to install and connect to PRTG core
I got the congratulatory message because it was connected to PRTG core
Even so you need to get approval from the core PRTG system
There is no reason not to approve this connection
The connection is successful and the PRTG monitoring system can monitor network devices over the internet
To prove it I added a new Windows server to monitor
The target server has an ip address of 192.168.9.129
I monitor the target server using SNMP
For Windows servers you can monitor using SNMP or WMI if you want
After adding a new target server, I add its sensors for monitoring
I want to monitor network traffic, processor load and hard drive free size
With Windows servers there are several other sensors to monitor such as internal memory, services and more
As you can see the PRTG monitoring system can monitor a Windows server over the internet by remote probe
There is one more problem I would like to introduce to you that when you use a domain name, how do you do it?
This part of the video will show you how to use domain names with PRTG
In this example I use duckdns service to create a new domain fast and free
I went to duckdns.org and created a new domain name netvnprtg.duckdns.org
The duckdns service also helps me to update my public ip address when it changes
In order for the duckdns service to update the public ip address, I install the client software on the Windows 11 computer
It requires a Windows 11 computer with Java installed
Just a few steps to download and install Java on a Windows 11 computer
After completing the Java installation I can use duckdns to update the public ip address
I set up the client with my domain and token
I just copy and paste as instructed
Setup complete, every 5 minutes the client will update the public ip address and map to the specified domain
After obtaining the domain name I set it up for PRTG monitoring system as follows
From the menu bar you choose User Interfaces
Here you update your domain name
The domain name I use is netvnprtg.duckdns.org
After successful update, I use this domain to access the PRTG monitoring system
Successfully set up, I can access the monitoring system without remembering the public ip address and no need to worry about the public ip address changing
What about the far side probe?
Of course you need to update the domain name for the remote probe
On your Widnows 10 computer, search for PRTG Administrator Tool and update the domain name as follows
Here I update the domain netvnprtg.duckdns.org
To apply this setting, the PRTG service will restart
It will take a while for this service to restart and connect to the PRTG server
So I have finished showing how to monitor network devices, monitor servers over the internet using PRTG
Note that the free PRTG version only allows you to monitor up to 100 sensors
