You can run a VPN server on a customer PC: OpenVPN http://openvpn.net/ for example. 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. |

OpenVPN server also serves as a DHCP server. 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. |

Nevermind, I got that part fixed thanks to Ben Parrot for pointing out the missing step. Now if I can just get it to ping...no luck there yet Later, Andy |

Has anyone had success simply conecting PROFINET to a 4G modem/router and bypass all of the intermediate PC's? |

can you make a short list of the complete IP Settings: 1.) IP Settings from PLC 2.) IP Settings for PC which is connected to the PLC Network 3.) Route command from the PC which should connected to the PLC Have you check the Ports settings in the Firewalls?

Hi, 1) All my PLC's are on dummy 192.168.0.xxx adresses. For example 192.168.0.1 2) PC is 192.168.0.97 on the main network card. PC is connected to Internet over additional USB network card. VPN connection over Teamviewer is properly established, I can ping 192.168.0.97 from my engineering station connected to Internet and VPN of Teamviewr, with the routing PC. But I cannot ping 192.168.0.1 (PLC) 3) route add 192.168.0.1 mask 255.255.255.255 7.157.31.180 metric 1 7.157.31.180 is VPN IP of the PC I am reaching. My firewall is turned off on both PC's, and the routing PC is behind the proxy, but the proxy parameters are set in Teamviewer options. It wouldn't work at all if it was not. Best regards, |
