I have a machine with a S7-300 CPU and a TP1200 HMI panel set up for remote support through an mGuard VPN router.
I can set up the router connection without a problem and when I start TIA Portal it lets me go online to the CPU, but it cannot find the HMI. If I just ping the network adress of the HMI I get a response so there is something there to connect to, but TIA Portal won't let me connect to it.
I have talked to a technician on site with the machine and there are no issues with the HMI otherwise as far as he could tell.
Any ideas on how to approach this problem this would be appreciated.
