There are so many answers to that question. "Best" is a big word.

While there are lots of options, just quit fighting and use HSEROUT/HSERIN. Easy to use, and has full PBP and DT-INT support. It is a waste of my time to try to convince you of anything. If you choose to use that method I propose, I will give you some pointers, if you don't, you will have to look for help from others.
