Situation is this : (PC of the programmer)---LAN(of programmer office)-------INTERNET------Router(Of customer)----LAN(of customer's factory)----PC(of the customer with no Siemens software installed, just Windows)----Simotion D4xx Question is this: Without using any hardware dedicated to the VPN remote (like eWon, Scalance, etc etc etc), is it possible to install in the PC of the customer a software which establishes a VPN between programmer's PC and Simotion ? Please, do not answer if the answer is "use an eWon/etc" because this is not possible for our machines. I have heard about tools like Hamachi/LogMeIn or VNC.... Do you know if something can be done for this situation ? Thanks in advance, Davinator

Install it on the Customer PC and open a RDC to the customer PC, now you can go online to the Simotion from the Customer PC. what exactly would you do? For diagnostics you can use the internal WebServer in SIMOTION. Or you connect the Simotion directly to the lan of the customer. Which SImotion and which FW do you use? Regards Christoph

We cannot install our software on customer's PC even if it is under the trial licence (what if the problem appears tomorrow and after 5 months ?). Also this means copying the software on customer's PC and he can see it, use it, etc etc. This way is not feasible for me...

Connecting with the VPN client from the programmers PC will put you on the SimotionD domain/subnet and the connection with Step7 and Scout can be established. The common challenge with implementing any type of VPN access is to work with customers IT department to make sure their Internet firewall will allow network traffic to machine's VPN server.

The only way i know at the moment is a TeamViewer Configuration. For openVPN your need additional SW o run for TeamViewer you need a licence. But Davinator will a solution with no costs, no licence etc. ! @Davinator Please specify whats you will do exactly? A download of the project or only diagnostic? If only diagnostic you can use the WebServer on the Simotion to diagnostic the System. Regards Christoph

DenisMor Posts: 344 Rating: (50)	We are currently running an OpenVPN server for Simotion lab access. It started as a OpenVPN server on an computer with an Ubuntu operating system, but then we optimized the system by moving OpenVPN server functionality to a wireless access router running DD-WRT firmware. I have not setup OpenVPN on Windows machine, but I do know it is possible.

Teamviewer could work, but i tried its vpn with scout with no success. Denismor : vpn is the way, ok, but how do you solve the fact that the programming computer could be in a lan and without a static ip on the web ? Tis is the same situation of the remote pc near the machine... With softwares like teamviewer this is solved because both pcs are connected to an intermediate server run by teamviewer... With openvpn is this possible ? Thanks again guy !

When the client (programming PC) connects to the VPN server it get's issued a virtual network dynamic IP address which is configured in server configuration to be on the same subnet as Simotion. There are two possible ways to setup the network: routing vs bridging. Although routing is easier to setup, I found that bridge configuration worked better for Scout remote access. In Scout project NetPro configuration you have to configure VPN server (PC) IP address as a router address, so the controller "knows" where to send communication traffic for programming connection. As far as non static IP configuration we use a DNS service provider: www.dydns.org or www.noip.com.

You solve the problem of the static IP with Dyndns / etc, but consider that the programmer could be in office, at home, in an hotel, everywhere. In that case the dynamic DNS will fail or cause troubles in all the situations where, anyway, you have to acecss to the router and open certain ports or redirect the traffic to your computer. I was thinking to something like Teamviewer where people have to do a very stupid thing : one installs TV, the other idem , they exchange the ID and password and that's it. In this case there are not routers to configure, no dynamic DNS, nothing ... The ideal solution would be to integrate something like TV with a good VPN software (the one of TV for the VPN seems to be useless for this request). Someone has tried things like Hamachi ?
