VPN Connectivity Issue

We also have a problem with our VPN connection:

  • From the remote side, we can ping the VPN tunnel IP of the Teltonika router.

  • But we cannot ping the LAN IP of the router.

  • We also cannot ping the PLC connected behind the router.

However, locally:

  • The router can ping the PLC successfully.

  • So the PLC connectivity is working internally.

This suggests a routing or firewall/NAT issue inside the VPN tunnel, possibly related to:

  • Missing LAN subnet routes,

  • Incorrect traffic forwarding,

  • NAT over VPN settings,

  • Or IPv6-only WAN limiting VPN traffic.

We need assistance checking the VPN configuration and ensuring LAN devices behind the router are reachable through the VPN.

Greetings,

Could you first confirm what VPN you’re using for your setup?

Additionally, could you confirm that in the WebUI, under Network → Firewall → Zones, the Masquerading option is Enabled?

Hi, Cyril,

Where are you seeing this SSL error? Would it perhaps be under Services → Cloud Solutions → RMS?

Please clarify.

Regards,
