DHCP Requests dropped by "LOCAL_ACL"

Question

Hi Guys, we have currently the strange behavior. DHCP Request are not being answered by the XG from a RED location. VIA tcpdump we can see the requests on the right interface XG210_WP03_SFOS 17.5.8 MR-8# tcpdump -ni reds1 tcpdump: Starting Packet Dump 15:33:07.981735 reds1, IN: IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from XXXXXXX:62:97, length 300 15:33:12.981487 reds1, IN: IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from XXXXXXX:62:97, length 300 15:33:17.722272 reds1, IN: IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from XXXXXXX:62:97, length 300 15:33:26.464993 reds1, IN: IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from XXXXXXX:62:97, length 300 15:33:43.337091 reds1, IN: IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from XXXXXXX:62:97, length 300 
 In the Packet Capture i can see that the Traffic is dropped by LOCAL ACL. When we give the Client behind the red a static IP - it work Attached are the RED & DHCP Settings XG has 17.5.8 and RED firmware 2.0.018 
 Attached also the Device Access:

Does anyone know how to fix that or why are these Requests dropped ? 
 I am grateful for every tip! 
 Kind Regards,

Max, 
 red can act as DHCP server for the network connected on the lan. This is the first approach to allow remote networks to get an IP address. 
 If you want to let the central DHCP server to send proper IP address to red network, you need dhcp relay. Red blocks dhcp traffic as router does. 
 I hope it is clear now.
