We discover a problem, when we disconnect de Ethernel LAN port for 30-60 seconds, or our device reboots
When we reconnect the device the Teltonika does'nt provide an IP address.
The device only gets an IP when the lease time is expired.
Our anaysis is the following:
We think that the RUT stop responding to any DHCP request because its assignment table is full
our limit is set to '1'.
It can be seen in Wireshark trace
Request are sent from our device :
0.0.0.0 to 255.255.255.255 but the RUT never respond with an ACK containing the IP,Lease,rebind, ...
It should look at the MAC of the request and since it is the same device which was previously connected
it should provide the same IP adress right away. But it waits for the lease time to expire!!!
This problem existed for a while, we are now running RUT2XX_R_00.01.14.3
No upgrade fixed it!
