Hi all,
I have a very strange issue.
Router: hAC v6.44.3 (stable)
I had a device (device 1) connected to the Mikrotik router using DHCP with static lease (192.168.88.202).
The device was working properly and was getting NTP updates.
I then added a new device (device 2) to the network with DHCP. It received an IP address from the DHCP server and was receiving NTP updates.
Then I did the following things:
a) switched off the first device (device 1)
b) removed the static lease of first device (device 1)
c) made a static lease for the second device (device 2)
d) changed the static lease IP address of the second device to the one that was using the first device (192.168.88.202)
After this change the NTP updates in the second device do not work anymore.
Everything else is working properly.
The strange thing is that if I remove the static lease and reboot the 2nd device then the NTP works (of course device 2 has a different IP).
As soon as I set the static lease of the 2nd device to 192.168.88.202, NTP updates are not sent to the device.
It seems that RouterOS is keeping in memory the 1st device somewhere, even if it has been removed, and is not routing the NTP updates to the 2nd device when the IP address of the 2nd device is 192.168.88.202.
Any help?
[EDIT]
Adding more information:
In ROuterOS I am using SNTP
In my device I set the NTP server to any possible server and nothing changes
Could it be that RouterOS is filtering NTS packages?
