Reverse NAT/Intercepting Proxy Detection
Info Nessus Plugin ID 31422
Synopsis
The remote IP address seems to connect to different hosts
via reverse NAT, or an intercepting proxy is in the way.
Description
Reverse NAT is a technology which lets multiple computers offer
public services on different ports via the same IP address.
Based on OS fingerprinting results, it seems that different
operating systems are listening on different remote ports.
Note that this behavior may also indicate the presence of a
intercepting proxy, a load balancer or a traffic shaper.
