Hi,

Just want to ask if it is possible to attain tranparent redirection without using wccp or policy based routing?

My idea is making the Ironport WSA the gateway for the workstation for all request will be seen by the WSA for it is the gateway.

Can I achieve tranpsarent proxy by using this?

Thanks

Hi Richard,

I'm afraid this deployment option isn't supported.

Thanks

Chris

Edit, from the deployment guide:

There are two deployment modes for the Web Proxy service:

•Explicit Forward Proxy—Client applications, such as web browsers, are aware of the Web Proxy and must be configured to point to the WSA. The web browsers can be either configured manually or by using Proxy Auto Configuration (PAC) files. The manual configuration does not allow for redundancy, while the use of PAC files allows the definition of multiple WSAs for redundancy and load balancing. If supported by the browser, the Web Proxy Autodiscovery Protocol (WPAD) can be used to automate the deployment of PAC files. WPAD allows the browser to determine the location of the PAC file using DHCP and DNS lookups.

•Transparent Proxy—Client applications are unaware of the Web Proxy and do not have to be configured to connect to the proxy. This mode requires the implementation of a Web Cache Communications Protocol (WCCP) enable device or a Layer-4 load balancer in order to intercept and redirect traffic to the WSA. Both deployment options provide for redundancy and load balancing.
