Hello,
Firstly, could you please try enabling masquerading on the RUT240’s firewall LAN zone to see if this improves anything?
If there’s no change, please provide:
- Screenshots of the routes you’ve created for both the PLC and HMI.
- Confirm that the correct default gateway is set on the HMI.
- Whether you are able to ping the HMI from the RUT240 or through the VPN tunnel.
Thank you.
Best regards,
