Hi, so what was the solution to this issue? I thought the idea by having a community forum was to share issues and solutions to help all users???? Why PM? Strange. A hint from others solutions would have given me a hint of how to solve this, so sharing is good. I can see a few others having the same problem.
I have the same issue. I use a RUTX09 to support two internal networks for families. (Two different routers, two different brands: TP Link Deco and ASUS) I could have done a proper work with a better setup in the Teltonika router but haven't had the time. Running on simple settings but it should work anyway. The Deco Mesh networks don't get this error message at all, however the ASUS router gets the "IP Block - No entry found for IP" and later "Authentication was successful ...." later. It happens at least ones a day. No block details in the block log. Both have a static lease setup under INTERFACES:LAN.
So, is it the Teltonika Router or the ASUS? What is the trick here?
