Transparent Redirection

[richard.bumanlag]

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

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.
