DHCP not working with VLAN ACL

Hi,

  

I have applied this a Vlan filter (detail below) on VLan 9 however no device can successfully get a DHCP address on that VLAN, I do not see any Dhcp packets or events on when debugging on the switch which is acting as a gateway for the DHCP server. As soon as I take the Vlan filter off I see it all functioning correctly. I have provided details below. Is it normal for VACLS to block DHCP requests and how can I work around this?

VACL:

1) ip access-list standard CCTV_ACL
    permit 10.100.5.10
    permit 10.100.1.254
    permit 10.214.67.249
    permit 10.100.1.203
    permit 10.100.1.201
    permit 10.151.32.0 0.0.0.255

    permit 10.151.34.0 0.0.0.255   

permit 10.214.67.128 0.0.0.127

2)
VLAN access-map cctv_traffic 10
action forward
match ip address CCTV_ACL
VLAN access-map cctv_traffic 20
action drop

3)
vlan filter cctv_traffic vlan-list 9

Vlan 9 is  permit 10.214.67.128 0.0.0.127 and the rest is management; DHCP server is 10.151.32.9.

Thanks in advance for your help!

Regards
