Cisco Application :: WCCP Web-cash On 2801 12.4(22)T

My problem is, it doesn’t seem like packets are making it to the linux/squid caching device, based on cache logs. Workstations that are being redirected in the router have no web browser access (they can ping 8.8.8.8 and google.com)
 
I have a linux box running squid successfully, which supports GRE WCCP. For the sake of argument, I will say that I am confident I have successfully configured that machine.
 
What’s really strange is this morning I came in and hind sight my test workstation looked like it may had restarted from an update. (maybe had internet access). The first thing I did was tweak the cisco config, as I was reading last night and saw:
 
“Be warned that if you are using NAT you MUST use the inbound interface otherwise the router only sees the NATted IP address as the source of your clients. This is bad, because the router is also therefore unable to see your cache engine and it will redirect the cache engine requests back upon itself.”
 
So I turned <ip cef> on and removed the <ip wccp web-cache redirect out> (I had in fa0/1 and out fa0/0 on overnight).
 
Then I proceeded to check the workstation and saw it had network access, I tested to see if it was in fact filtered by the proxy, and it was! (verified by cache logs aswell)
 
After some further successful testing, I made sure I saved any unsaved configuration changes, I rebooted the linux box and the router. Sadly the outcome was not good, I am back to where I was last night.
 
 
My router does routing/NAT and has two interfaces and is currently not running CEF
