I have been having problem setting up a home network over wireless, using both Windows 7 built-in homegroup feature and network magic pro file sharing. I have three PCs, two Ultimate Windows 7, and a Home Premium Windows 7.
After two days of trial and failure, I found that I have to allow local services (TCP) and UDP for "Any Address"! This was one of the first assumable solutions, but my instincts didn't allow me to allow communication using these packet rules for "Any Address".
Until I found an instruction at this web site
I tried allowing the rule for subnet, but I didn't succeed. Is this solution safe? If not, what do you suggest can solve the file sharing issue?
