Hi,
The DHCP server on the Sophos XG210 is not working. This is not the first time it happens.
An AP has been rebooted and is not becoming any DHCP Offer or ACK back.
AP > Switch > Sophos XG port LAG > bridge interface 0 br.0 > vlan 1 br0.1
Frames are coming to the firewall, but the XG is not answering: see packet capture below (MAC address was changed for privacy reasons)
console> tcpdump 'port 67 or port 68 -s0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

When saving the packet capture to a file, I can see all message types are "Boot Request" > meaning DHCP DISCOVER.
