Plc webserver remote access without VPN

To access S7-1200 web pages, all you need is a web browser, and valid IP address accessible to the browser.

A VPN router could certainly do that if properly configured and networked (wired up).

Hi all,

Is it possible to access CPU webserver page remotely without VPN connection (such as using VPN router)?

Many Thanks

You want the PLC to have a domain name associated with it?  Like myplc.info or something?

If you do that, it will get all kinds of hacking attempts to get past whatever firewall and/or VPN solution in place to protect it.

Or, you can go into your PCs "hosts." file and add a text name to associate with the VPN established IP address.

Why not set a browser favorite used while VPN access is in use?

 Hi 

many thanks for your response.

I agree with you on the IP address when there is a need to access plc webserver page locally, in other words, CPU and a laptop with a browser are connected to the same network.

I am in a location A and PLC is installed on a remote location B (both networks are totally isolated with different network CCs. Currently, I use a vpn router to access the system remotely and it works in terms of CPU programming. Webserver page can be accessed by typing CPU IP after linking my network with the VPN router (using third party software)

my question is, regarding the scenario mentioned above, Can I still be able connect to the webserver without using VPN using a unique HTML address associated with the CPU.

I wish I explained better than before

Thanks
