Subject: NAT and CBWQ - what order?

calls) and workstations. Private IP addresses will be running on this hosts
connected to a 2611XM router (12.2(8)T). I need to do the following

specify NAT addresses or the private IP?

I will have to make my match clause with NAT address, if it comes after I
will have to make it with private addresses.

enabled for output and not input when I put a service-policy input .... on
interface. Please when can I use input and output service-policy? When is it
valid.
