Transparent Web Proxy with 200 public IP

Hi,

I have a customer that requires a transparent Web Proxy service , they are on the security bussiness.
But they requiere at least 200 public IP address set on the proxy server, and the proxy server must be able to rotate the public IP by request or by time.

They are able to do this by payed proxy service, but they require the service on my country to work locally. So it will be a transaprent Web Proxy Privated just for them

RouterOS can’t act as that proxy.

For routing traffic to the proxy this details are irrelevant and it can do that part fine, of course.

Well I am lost; I never did something like this before, so more explained help will be gratefull

I only see this on payed public proxys
