Access Points not assigning DHCP IP to Apple devices behind XG85

Hi,

open logviewer and watch what is displayed when an Apple device requests and IP address.

Ian

I just tried to connect again my Mac device but nothing updating/showing in the logviewer.

Hi,

sounds like your APs are using a strange wifi setup that the Apples do not recognise. Why do I think this because you are not seeing any DHCP requests hitting the XG for an IP assignment.

Ian

What do you mean by strange?

its simple setup for any AP, all other devices are working fine.

Same apple devices are working with same AP if i disconnected from SOPHOS.. how ?

If you remove the APs from the XG where do they get their IP addresses from?

Ian

DHCP is not enabled on XG.

DHCP is enabled on Internet router which is directly connected with XG WAN port.

Everything is working fine except Apple devices.

Is the XG in bridge mode? How are you passing the DHCP request through the XG?

Ian

Yeah it's in Bridge mode.

Do you have a firewall rule in place to allow the DHCP requests to reach the modem? Does it have logging enabled?

Ian

I found the solution. Thank you.

Hello Qaiser Khan,

As per your diagram you have 2 network i.e. 172.16.1.0/24 and 192.168.0.0/24 now if you have bridged between WAN interface connected to the router and host systems in 192.168.0.0 network. Could you please check if there is a WAN to LAN and LAN to WAN rule configured? You could also combine both rules to a single firewall rule. I would assume here that the network 172.16.1.0/24 is configured as a seperate interface. So you might have to configure Static or Policy routing for your servers to communicate through the router. 

It would be much easier to have a seperate network between Router and your LAN network and configure XG as a DHCP server for that interface or you may simply configure DHCP relay to point to your router to provide DHCP if needed.
