Problems between iphone and dhcp?
-
@johnpoz Exactly, but the iphone keeps ARPing for pfSense so it looks like it's not seeing those replies. One could assume it may also not be seeing the ARP requests from pfSense, which is why it never replies.

Quite possible - something clearly is wrong here with the arps.. There should be no reason for pfsense to arp that many times for something. Unless its not getting an answer..
And same goes for the phone for sure.
Something wrong with arp is most likely the root of this issue.

@gertjan I will try to do these tests in the test environment, thank you for your suggestion. Furthermore, the replacement of the old wifi extreme bubble with the new Aruba APs is expected in the next few days. At this point I stop for a moment with the tests to try again with the new infrastructure to see if the problem persists.
Thanks everyone for the help -
Some proxy-arp happening (or not happening) somewhere? Not sure why it would be in a network like that.

Could it hit something?

Could this justify the fact that in the lab with only one ap the problem never appeared, while in the bubble with controller it appears sporadically and only on iphone? -
Maybe, if you have that enabled. I don't see anything in the pcap that looks like that specifically but it could be something related.

@stephenw10 In the article in apcontroller mode it is active and cannot be disabled. I have to ask for a check who configured the bubble for us

Definitely worth testing if you can.
It looks like it's definitely not a pfSense issue though.

Hi everyone,we have completed the new wifi bubble. I confirm the problem was generated by the old Wifi extreme controller, it is not a Pfsense problem.
Thanks a lot to everyone for the support.

Thanks for following up. That could save someone else a lot of time.
