I have a client site with a network of S7-400 PLCs on a LAN (CP 443's) about 400 km from my office. My client's IT people have set up a Citrix VPN connection so that I can securely connect onto the remote LAN from my office and 'ping' selected PCs at the remote site. They get to control what 'targets' I have access to and what ports I can access - i.e. all the normal security stuff.
Step-7 seems to want to behave as though it is connected locally to the remote network, which of course doesn't work via the VPN tunnel. When I try to work through Siemens support they keep referring me to either Teleservice or the Scalance Switches.
Surely there has to be a way to make a secure VPN work without any additional hardware? I could install another copy of Step-7 on a networked PC and then use RDP via the VPN to remotely control that PC but that seems like a whole lot of unnecessary work and expense.
Can anyone confirm what is happening and offer a solution?
Thanks,
