Hello,

Thank you for reaching out.

To assist and troubleshoot this matter more effectively, could you please provide:

  • Screenshots of your current IPsec configuration on the RUTC50 side.
  • The IPsec log output from your RUT, which you can find in Services → VPN → IPsec, under the Logs section.

Furthermore, for reference and guidance, I’d recommend reviewing this example configuration, which, while for a Cisco device, outlines the essential IPsec tunnel parameters you might need to align with your FritzBox setup:

Also, there was a relevant community forum topic on configuring IPsec with a FritzBox discussed here: IPSec-Site-to-Site-Tunnel with Teltonika RUTC50 and FRITZ!Box 7590

Additionally, as a useful reference, check the IPsec configuration’s necessary settings between RUT and FritzBox in the spoiler below.

Important note: Make sure the proposal settings (both phase encryptions, authentication, and DH groups) between IPsec tunnel participants are identical.

Best regards,
