While using VPN handler apps I have come across terms such as

  • real host

  • dual real host

  • reverse proxy

These terms appear under the proxy type tab. What is the difference between them and what is their use while using proxy servers?


I'm not really familiar with the term real or dual real host but I'm assuming that means a normal (forward) proxy which essentially functions on behalf of one or more clients to shield their identity (among other purposes) from the internet at large. The dual part is maybe a dual-homed proxy? dual-homed means it has more than one network interface for redundancy.

As for reverse proxy it is the reverse of a forward proxy...it functions on behalf of the internal network of a collection of servers to make it appear as one single point is servicing clients when it may in fact be an entire network of servers providing services.
