Hi,
I have a RUT240 wich uses a SIM Card from 1nce.com to connect to the Internet.
I have a PLC Siemens S7 1200 connected to the RUTs LAN port, wich I want to access from my PC.
1nce are offering a free openVPN Service to connect to their Network. In that Network each SIM Card has a fixed IP adress.
1nce VPN Dokumentation
I am able to connect to that network using a openVPN client on my PC. Once connected I can ping the WAN IP shown by my RUT240 however I am not able to reach the Webinterface of the RUT nor can I ping my PC from the CLI.
After that I tried to use a VPN directly on the RUT in addition to the provider VPN so my connection looks somethong like this:
PC -> openVPN to 1nce.com -> L2TP/IPSec -> RUT240.
With that configuration I was able to reach the RUTs Webinterface.
But what I didn't get working was connecting to the PLC connected to the LAN Port of the RUT240 I don't know what to put into the routing table or the firewall settings of the RUT so make that connection work.
can someone please help me?
