Hello,
We are trying to access remotely a PLC (ifm 711S) and a HMI (ifm CR1077).
Both are connected to a Teltonika RUT200 router.
We establish the connection with OpenVPN Connect and can ping both controllers.
We have a laptop that, most of the time, will allow Codesys connection to the controllers, but we have several other computers that are unable to connect, although all of them can ping successfully.
We cannot find any difference in the configuration or software installed from one PC to another.
If we connect to the router by WIFI, instead of VPN, all the computers work fine.
We know that scanning the network will not work over a remote connection, so we input the controller IP directly.
Has anyone had a simlar problem and can offer any hint on what to check to meke the connection run?
