1. From your laptop, tablet, or smartphone, connect to the internet using a cellular data connection or public Wi-Fi.
2. On your device, open the list of available Wi-Fi networks and select the name of your router. Enter the password for your network when prompted.
3. Once connected to your router, open a web browser and enter https://www.whatismyvpn.com/ into the address bar. This website will tell you what IP address has been assigned to your device by your ISP. Write this IP address down as you will need it later.
4a) If you are using Windows 10: On your taskbar, click the network icon (the one that looks like two computers with an arrow between them). A list of available networks will appear – hover over the one that says “Private Network” and click it; then click “Connect”. If prompted, enter in the shared key for your network and click “OK”. You should now be connected to your VPN! Skip to step 7 below.
4b) If you are using macOS: Click on the Apple logo in the top left corner of your screen and select “System Preferences”. In System Preferences, click on “Network”; then select the interface (with green text next to it) that represents your VPN connection – it will likely have the name of your provider in it such as “ExpressVPN” or something similar; finally, click “Connect”. You should now be connected to your VPN! Skip ahead to step 7 below.
4c) If you are using Linux: Open up a terminal window and type in `nmcli` – this stands for Network Manager Command Line Interface; press Enter. Type `help`and press Enter again; this will give you a list of all available commands within nmcliNow we’re going to use nmcli’s `connection` command which lets usManage network connectionsa perfect fit for our needs! To see more information about this particular command (and any other command), simply type in `connection [command] –help`, so for us that would look like `connection –help`. When ready, go ahead and type out`sudo nmcli connection up id “[name_of_your_vpn]” iface “[interface]”`, making sure tobetween double quotes around both ‘[name_of_your_vpn]’ placeholder (replacing [name_of_your_vpn] with actual Name given by Your vpn provider eg.”us936obfuscated”). So an example might look like sudo nmcli con up id “ExpressVPN Boston” iface “wlp3s0”’ wlp3s0 being my wifi adapter’. Replacenamewith whatever instead of yours given By vpn provider After execution You Should Be Connected To Vpn ! skip ahead TO STEP 7 BELOW
5) If none of the above applies to you or if you are still having trouble connecting: try contacting customer support from Your chosen vpn Provider They Would gladly help walk You through correct process OF Setting Up OR Troubleshoot any current issues BACK TO OUR REGULARLY SCHEDULED PROGRAMMING 🙂 . . .
6) Now That We Are All Connected To The Same Vpn let US go Ahead And Access It Remotely ShAll We ? following Steps Below :
7) Head Over Too https://dashboard.[YourVpnProviderDomainName].com & Log In With Credentials Given By Vpn Provider
8 ) Once Logged In , Navigate Too The Section Of The Dashboard That Says “Remote Users” Or Something Similar Where You Will Be Able To Add New Devices/Users etcetera **Follow Any Additional Instructions Given Here By Your Specific Vpn Provider As They May slightly Differ But For The Most Part They All Follow These Rough Guidelines**

Assuming you have these things in place, let’s go ahead and walk through how to remotely access a PLC. The first step is to open up the communications software that you are using. In this example, we will be using RSLinx Classic. Once RSLinx is open, go ahead and click on the “Configure Drivers” button near the top of the screen:
On the next screen, make sure that “EtherNet/IP” is selected from the “Available Driver Types” list on the left side of the window. Then, find your specific PLC brand in the list of “Selectable Devices/Pools” on the right side of the window and select it:
Click “OK” when prompted about connecting to remote devices through Ethernet hub or switch. On rare occasions it may be necessary add an entry into your hosts file for this particular device; however, most times this isn’t necessary so we’ll skip over that part here. You should now see your newly added driver appear in RSLinx under comms Setup > Driver Selection:
If everything looks good up to this point, go ahead and click ‘Yes’ when prompted if want RSLinx classic start automatically scanning for new devices every time it starts up:
exit out of this window by clicking ‘OK’. Now that our driver is setup correctly within RSLinx Classic we can finally add our remote device! Go ahead and click on File > Configure Remote Devices from within RSLinx Classic:
this should bring up another window titled ‘Remote Device Manager’:
go ahead and press F5 or click on View > Refresh List from within this window until you see your newly added driver appear in blue text under Available EtherNet/IP Networks like so:
Select one more time (or double-click) on available network containing name of newly added driver which in our case would be ‘NIOT-ETH0208’. This should bring up yet another window called ‘Remote I/O Scanner Configuration’. Press F5 or click View > Refresh List again until you see all targets associated with selected network appear as green checkmarks indicating they are online like so (assuming all applicable industrial controllers associated with selected network happen be turned):
Exit out this window by clicking OK then select all online targets Check boxes except Default Gateway then press Add Selected Targets button followed by Close button get back main Remote Device Manager Window which should look something like following at bottom after adding various online targets one or more networks :

Setting up a VPN connection to your Synology NAS can be done in a few simple steps. First, you’ll need to create a new user account specifically for VPN access. Next, open the DSM (DiskStation Manager) web interface and go to Control Panel > External Access > VPN. Select OpenVPN from the list of available protocols and click ‘Create’.
Now enter a name for your new connection and fill in the required information such as server address, port number, encryption method, etc. You can also specify which users will have access to this connection by clicking ‘Permissions’. When finished, click ‘OK’ to save your changes.
The final step is to download and install the OpenVPN client on your computer or mobile device. Once installed, launch the client and enter the same login credentials that you used when creating the user account earlier. After connecting successfully, you should now be able to access your Synology NAS as if you were on your local network!
