I have a Cisco 1801 router connected to the Internet configured wit NAT. An outbound service-policy is configured on the public interface to prioritise an application which is working.
I want to prioritise traffic from one of my wireless clients also so I have configured an extra policy on the interface that the wireless access point is connected to (The wireless AP is not running NAT)
interface FastEthernet7
service-policy input PRENATMAP
class-map match-any PRENAT
match access-group name PRENATACL
policy-map PRENATMAP
class PRENAT
set qos-group 1
ip access-list extended PRENATACL
permit ip host 192.168.1.120 any
I can see traffic being sent by this device but the policy map is showing no matches. I am using the "qos-group" so that I can priortise this traffic after it has been NAT'ed on the public interface and therefore I don't know the source IP anymore.
sh policy-map int f7
FastEthernet7
Service-policy input: PRENATMAP
Class-map: PRENAT (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: access-group name PRENATACL
0 packets, 0 bytes
5 minute rate 0 bps
QoS Set
qos-group 1
Packets marked 0
Class-map: class-default (match-any)
0 packets, 0 bytes
5 minute offered rate 0 bps, drop rate 0 bps
Match: any

Anyone able to help with this?

I guess one thing to point out is that the default class also has no matches.
This may be a indication that this is not supported on the switch ports of this router. There are many restriction depending on the switch platform related to QoS.
Try applying the service policy to the layer 3 virtual interface and see if you see any traffic.

Thanks for the reply
I tied that also but get the following:
Router(config)#int vlan 1
Router(config-if)#service-policy input PRENATMAP
Configuration failed!
This is an 1801 running 12.4(11)T4 AdvIP Services
