DHCP Static Leases, error subnet range

[tsmy]

I have RUTM11 firmware RUTM_R_00.07.19.1

DHCP server last IP is 192.168.40.158/27.

I made Static Leases, add manually insert MAC and IP (statics 25 IP:s).

Then I want increase IP space last IP 192.168.40.190/26.

Then I try input new IP 192.168.40.161 then error message popup.

What I do wrong?

Greetings, @tsmy,

Welcome to Teltonika Community!

To help me investigate the issue more thoroughly, could you please provide a full screenshot of your configuration that shows the Target and Netmask options? Having this will allow me to review exactly how the static lease or route is defined in your setup.

For additional reference, you may also check the guidelines for configuring static IPv4 routes here:

I look forward to your reply.

Kind regards,
V.

Caused the problem: LAN_IoT IPv4 netmask is my old netmask.
