Hi there,
Currently I'm having an issue with the dhcp leases regarding the number of
available IPs.
I have some devices that are renewing their IP addresses at an interval of
15 minutes. The problem is that after the DHCP Server is offering the new
IP, the old one is blocked and cannot be used. This way a lot IPs are
blocked and eventually it goes to "no free leases". And I have to clean
manually the dhcpd.leases file by removing it.
For the moment the workaround is to manually bind the IP to the MACs that
are facing this issue. This way that MAC is not changing the IP.
I attached a prinscreen of the current values of an IP pools that are used.
I'm hiting a 132 touch IPs which seems that cannot be used.
Is there any parameter that can be set or an option to be configured in
order to prevent this ?
Thank you !

I don't know off-hand, but I think you will more likely get a more useful
response if you can share the configuration that you are working with. It would
not have to be all of it, but a representative part of it, obfuscated if you
wish, could help those helping you.
