Since then, life has been a little crazy. A new job for starters. I've learnt and experienced too much to list here - maybe one day, I'll get around to it. But for now, I thought I'd drop a quick WCCP config in here to reference later.
The scenario is that guest wifi is being rolled out. The guests are tunnelled into the DMZ and once there, they can access the internet. The customer would like some relatively simple transparent proxy or filtering capability and so WCCP was common across both the layer 3 switch and proxy appliance.
I've cut and paste most of this from my own documentation, so apologies if its not 'blog friendly'.
