ok unless you're having trouble with redshark/hamachi please dont post here asking how they work because both programs have help files and FAQs so all you need to do is download the program and READ, i know its a hard task for some people but yes READ the tutorial file and you will be a pro! i promise
if after that you are having trouble getting connected then ask one of us for help. Im sorry if this seems rude but its not that hard to read a tutorial file...
