We have a hosted web defense product that we have acquired - in order for the web-defense to work, it needs to have all of your port 80 traffic routed to their proxy server. That said, we are looking for a way to route all outbound port 80 traffic from our network to the public proxy of our hosted web-defense product. I have had mixed opinions as to whether or not this is possible. Obviously our incoming traffic would have to remain as it is since we have many servers inside that use port 80.
What are our options?
