iPhone does not respond to DHCP request/discover from our Linux-based system We have the following problem: 

An iPhone is acting as a Network Access Point under the PAN Bluetooth profile, but it does not respond to DHCP request/discover from our Linux-based system. The PAN connection can be established, but no IP address is assigned.

Steps to Reproduce:
- Activate Bluetooth on iPhone (5C iOS 10.3.2, but also seen in 6S iOS 11.x)
- Activate Bluetooth tethering on iPhone
- Pair our Linux-based system to iPhone via Bluetooth (PAN profile, NAP service)
- Execute dhclient in our Linux-based system.

Expected Results:
- The iPhone assigns an IP address via DHCP to our Linux-based system.

Actual Results:
- The iPhone does not respond to DHCP request/discover from our Linux-based system. 

Is there any special handling/protocol in order to get an IP address and establish the PAN communication?
Thank you all,

The problem was solved by setting the MAC address manually right after the TAP interface was created
