Hi All,

I turned off: ignore client uid and because we have a lot of apple endpoints on the client site, i also disabled the mac adres change option on the apple endpoints.

It looks a little bit more stable right now, and i will update the routers to the latest version next week, i will keep you posted!

Hi Cookie,

Thanks for your reply, forgot to post the lease times, but they are set at:
Default: 900.
Maximum: 1800.

Weird thing is that only one device as shown in the attachment claims multiple ip adresses, so no idea why this happens.
And you can see that the lease is only active for like 1 second or so, but the router doesn't automatically remove the leases.

The only dhcpserver in the network is the OPNsense and this happens at more customers where we have an OPNsense running but not all our customers so it's a funky thingy.

Hi All,

Long time no post, but I'm back again! 😊
I'm experiencing some strange behavior on multiple routers.

One of the routers is running OPNsense 24.7.12_4-amd64, and it will be updated soon (not sure if this issue has already been fixed in a newer version).
It's always at least one device that claims a lot of DHCP adresses, sometimes there are more devices that get multiple adresses and then our DHCP-pool gets full :(.

Here's the DHCP log for one of the leases:

2025-04-16T09:57:23   Error   dhcpd   Abandoning IP address 192.168.6.100: pinged before offer

2025-04-16T09:54:56   Error   dhcpd   Reclaiming abandoned lease 192.168.6.100.

Is anyone else seeing this weird behavior as well?

Hi Anakein,

What are your firewall rules voor your openVPN interface?
You need to put an rule in that says your vpn network (when following the default setup i think it is 10.8.6.*) can look in de destination network, and if you want to let it connect trough your wan you need to give it some more speficied settings.

Hi Spetrillo,

I know sometimes MacOS computers are very annoying with holding their local DNS cache, did you try to clear caches on your workstation?

And what happens when you ping from the router itself?
You can find the ping option under Interfaces -> Ping, and then don't forget to select your range in the source address.

Hi Everbody,

I'm new here and i am really happy that there is such a big community, i was looking trough the forum but couldn't find the right answer (sorry if it is somewhere and i didn't find it)..

I have the following question;

I have a wireless network lets call this 'Office' and i have the range 192.168.2.x assigned to it.
Now in that network i have 250 connected clients and well you get the point the pool is full, but i have more clients that need to connect to the same 'Office' wireless network. Is there a possibility that you hook up a second DHCP pool so that when you connect trough wireless network Office and pool 192.168.2.x is full you get an address in the 192.168.3.x range?

I hope someone has the answer:)!

Thanks in advance!
