Well that's quite odd. If you have a green dot connection in the Hamachi list to the person you wish to play with, then it matters not whether you're at school, work, or have a weird setup. That green dot indicates a direct tunnel, so the lan should work properly...should. If only these things worked reliably and consistently. I hate feeling helpless about these things when they don't work when they ought to. Is there anything funky, fancy or unusual about your internet setup that might help me determine the cause?
