[Ahmed Allzaeem]

Thanks 

I have some achievement , but still no access.log

I've not seen any of the config examples needing to specify it specifically at the Cisco end. I suspect it is implicit in the enabling of "wccp" modules.

GRE vs L2 use also depends on the device hardware type (router or switch, PIX or ASA) and how recent the IOS version is.
