This is not an authoritative statement, but I don't think it's a particularly good idea to do performance testing with a limited implementation of NAT as part of the test process, especially if your production environment will not be using that implementation. There are some limitations to the NAT within Virtualbox documented here: http://www.virtualbox.org/manual/ch06.html#nat-limitations Do you get the same problem with a bridged or host only setup? -- Message sent via my webmail account. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
