UTM says I keep exceeding my licensed users, but I'm not

Charles Bailey1

I count around 25 IP addresses, but every day UTM seems to add more. The latest email the UTM sent me says I'm at 75 users. I've tried disabling and reenabling the DHCP server, as well as cutting the range to one IP address, then back to normal. If anything, these steps seem to make it worse. Why is this happening, and what can I do?

    Hi Charles and welcome to the UTM Community!

    The UTM counts IPs that it has "seen" in the last 7 days.  It "sees" an IP if you ping it even if it's not there.

    Cheers - Bob

    Thanks for the reply Bob. Two obvious questions.

    1) How do I reset the 7 day counter?

    2) I have never had over 50 devices. I've run UTM for years, but this just started a week or so ago. What created this problem?

    Not much of a jump, but this morning I'm up to 76 devices. Is there maybe a bug in the DHCP lease module?

    You used to be able to restart the UTM I believe to get it to clear out old lease information.  I'm not sure that is really the case anymore.  An older trick was to disable DHCP, shrink your range, enable, disable, expand it back and it would clear out leases.  You could also try deleting the DHCP range altogether and recreate it.

    There is a way to SSH in and modify, but I don't know that one.  I bet Bob does though.  ;)
