I have recently been given the task of installing a web filter on our network to monitor and eventually filter some of the web browsing done in my network. I have a Cisco 2911 router and a Sophos Web Filter appliance. I have the web appliance installed and it looks like I have some traffic being monitored, but not all. The configuration of my router is as follows:

This was configured prior to my coming into the job. Have a wireless back haul and two other networks that are going through BHN_Outside port for the internet. Am trying to get all port 80 and 443 traffic routed through the web filter that is setup on the network.

Any help is welcomed.

Web filter is setup on network as IP 10.2.9.10 SNM 255.255.240.0 Gate 10.2.9.1 DNS 10.2.9.14. Appliance is connected to switch that holds all traffic in the building.

This is what I needed to do to get this to work. We have a Catalyst 4507 at our core and it has the following config:


10.11.0.19 is the address of our Netbox Blue proxy/filter.

When anyone on VLAN61 (WiFi) attempts to access the web on 80/443 the traffic is redirected to 10.11.0.19 (set up as transparent proxy). In our case, Netbox then presents a logon page for AD authentication which is required before proceeding (this allows Netbox to filter and track what the user does).

Distubedone- Thank you very much. That did it. Don't have much Cisco programming experience. Currently studying up on that now. There's a lot to learn. Thanks again.
