Hello together,
I'm using SOPHOS UTM 9.004-33 and activated the DHCP server for my internal LAN. And I'm using a AVM FRITZ!Box 7270 as WLAN access point and a AVM FRITZ!WLAN Repeater N/G as a range extender of my WLAN.
This environment worked fine for all my WLAN devices, windows based clients and andriod systems until yesterday. The android systems have fixed IP reservations by DHCP because they can't connect to Google Play store by using the SSL proxy so I made a exception for these devices by using their fixed IP address.
But since yesterday my android devices won't get their IP adresses any more. They are connecting fine to WLAN and send their DHCP request to the UTM but after a short time of requesting the IP address the WLAN connection will be broken and the process is starting again. These are the DHCP logfile entries of the UTM for one of my android based clients:
The windows based clients are still working fine when connecting them via WLAN. So it must be something between android clients and the UTM.
I have even disabled the DHCP scope of my internal IP network to delete all the DHCP leases but after enabling the scope again nothing changed.
Does anyone know about this problem? And is there someone who has a solution?
Thank you
