I have a home computer hooked to a router which is connected to a hispeed modem from Comcast. I also have this computer firewalled with Norton Internet Security. I want to be able to access and transfer files from that computer to my laptop when I am away from home. I believe from reading the user guide with PCA that I have to set up my home machine as a host and have it wait for a connection. I get confused about setting up my laptop. Should I install the PCA gateway on my laptop? If I am reading my user guide right it says that I have to install the gateway version because the “host” is behind a router and firewall…is this correct? Anyone had success with setting this up with Comcast as the ISP? Thank you
