I'm moving this thread to the Web Gateway sub community. Meanwhile did you perform packet capture in the segment between the McAfee Web Gateway (Webwasher) and the WCCP router ? And if so do you see anything that may shed a bit more light into the issue ?
With my best regards,
Yes we do see minimal traffic, but I think that is just the two pieces of equipment talking.
But we have to immediately turn it off as no one can get out to the internet.
I think I have seen something like this before. Did you reboot your webwasher after you enabled WCCP? there is an iptables rule that has to be set for this to work and that only happens after a rebbot as far as I know.
I have rebooted. Still the same issue.
mmmhhh. You are not seeing any webwasher block messages, right? traffic just times out? It could be a routing issue. Webwasher needs to be able to send traffic back to the clients. Try to ping one of your client IPs from the webwasher commandline.
I am sure you checked that, but is the transparent proxy checkbox set for proxy port 9091?
If you use an access-list to constrain the WCCP traffic to a single host you can perform testing without impacting the general infrastructure and then check with a network sniffer if there is traffic back and forth between the router and the McAfee Web Gateway (Webwasher) and you can also sniff between the router and the client to see if there is any reply back.
Let us know if you see any traffic then.
