That depends on your set up. It's not 'always' so easy as that. lol

You don't have to do this, but if you'd like more people to be uploding from you then we'll help you find what it is that's stopping them at present.

1. Can you give us a total desciption of your set up: What firewalls you have?
2. Connection type?
3. Modem & router brand name & model numbers?
4. Where are you trying to connect from (home, school, work, etc.)?
