> But what do U say about people using it at home ....SOHO if people understand that NATs allow them to run web and mail clients from multiple machines but prevent them from running most other apps, then I don't have any problem with it. again, the problem isn't that NATs exist, but that people are misled about the harm that they do - to the point that if an application won't work over NAT, folks blame the application. > IPV6 is running away from current problem .... not the solution ...... no, I don't think so. the only way to solve the NAT problems is to provide better ways of doing things that NATs purport to do, while at the same time not causing the damage that NATs cause. in particular, 1 provide an end-to-end global address space 2 provide better mechanisms for security/policy enforcement than those based on patterns of address bits 3 make it as easy to plug a network into the Internet as it is to plug in a host 4 minimize the burden of renumbering IPv6 is attempting to do all of these except #2.
