most people on here are being anal to prove their knowledge rather than address the original question.
Jofm5, that's a rather unkind remark, whoever it is addressed to.
If to me, may I point out that it was you who introduced the topic of NAT, but got it wrong. I was merely ensuring that others who are not as technically gifted as you are weren't left with a false understanding of the subject.
Finally, I would much rather be thought anal while proving my knowledge than thought anything else while proving my ignorance.
