Unfortunately, I'm not exactly sure myself what the consultant meant by inverse DNS. The situation is, we are being required to install a caching proxy. All the supporting documentation provided by the accrediting agency makes reference to the Microsoft ISA server (something we can no longer purchase). Our consultant claims to have done some research and found that there are some features in the ISA server not found in other caching proxy servers. One of them he classified as a "sort of inverse NAT" (without going into any detail). I've done some research on the subject but I've been unable to pinpoint the ISA feature not found in TrafficServer. Here is a summary list of ISA features: http://download.microsoft.com/download/1/C/6/1C6A42B2-79E6-4201-A8B2-73DC0DB8DD47/Evaluation_Guide.doc Based on your response I'm going to push for a better, more explicit explanation of what exactly is required and reply to this thread if I ever get a clear answer. Thanks again for the effort! Ted Stresen-Reuter
