I have done some quick searches, and reviewed the TPROXY documentation but I have not found an answer to the question of whether I should be using the TPROXY target for a simple transparent proxy. (i.e., not listening on a foreign address and not reporting a foreign address as a source) Currently, the system that I am working on is using the REDIRECT targets to transparently catch port 80 traffic and redirect it locally for either caching or authentication. Is there any benefit to using the TPROXY target in this case? I have not been able to find anything that explains what the differences between the two targets would be in this simple case.
