allowing file and print sharing from a trusted network is a pretty basic feature on every personal fw ive come accross. hopefully this firewal has support for local networks. im assuming you got it for content filtering for your kids. @ 86 dollars and 39 a year thats the only thing that makes sense so being behind a router you could always turn off the fw feature or make a rule to allow all traffic from your local subnet 192.168.111.0/24, or whatever, or your computers ip address if you cant find a simple check box for allowing file and print sharing.

did you donload the help (exe) file. the pdf says help with advanced features can be found in the programs help file.
