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.
