[Cisco 1921] DHCP Server - ACL won't allow

Hi there!

I got a Cisco 1921 router which runs a DHCP Server on its LAN port.
Without ACL, the DHCP server is working well.
With ACL (even permit any any), the DHCP packets won't pass.

Here is my ACL configuration:
interface GigabitEthernet0/0
 description LAN-Gi0/0
 ip address 192.168.10.1 255.255.128.0
 ip access-group 100 in
 ip nat inside
 ip virtual-reassembly in
 duplex auto
 speed auto
 
access-list 100 permit ip any any log
 

debug ip access-list data-plane says:
Mar 20 15:11:42.079: IPACL-DP: Pkt Matched against EPM list, Action: Deny
Mar 20 15:11:42.079: IPACL-DP: Pkt matched punt/drop it
Mar 20 15:11:42.079: IPACL-DP: Pkt is punted to process path from cef path: interface GigabitEthernet0/0 inbound direction

Any idea what could happen?

Thanks,
Mathieu.

Any particular reason why you even need to run an ACL on your LAN interface?

An understanding of your setup and requirements may help us point you in the right direction.
