Connecting Siemens Tia portal via router in Windows 2019 server

Question

Dear all

I need to monitor an S7-1500 PLC behind a router (WAN=192.168.1.27, LAN=10.68.1.1) from Windows server 2019 using TIA PORTAL V14 software. The router was configured as port forwarding. In this case, Siemens's S7 port 102 is used to route network traffic arriving at 192.168.1.27 to send it to 10.68.1.30 (IP address of the PLC). This setup works well for a communication program running on the same computer (kepserver) where I set the router's WAN IP as the destination device's IP. But I can't do the same in the TIA PORTAL because the declared IP address is part of the PLC configuration. Someone on the Siemens support forum suggested adding a route in Windows to keep the destination IP configured in Tia Portal and at the same time to reach the router from the Windows server. The route to add would be the following: 10.68.1.30 mask 255.255.255.0 192.168.1.27. Could this affect network connections with other services (for example by disconnecting my remote desktop connection to the server) or does the route table act passively delivering the corresponding route when some application needs to reach the destination IP declared in the route table?

Thanks for you help.

Sounds doable but the mask may be wrong. Read on here.
