That's why I wrote iConnect. It senses when you launch an internet application and can automatically connect for you. It senses when you quit your internet applications and can automatically disconnect for you. It is highly configurable and can be easily adapted to suit your internet habits. Unlike similar utilities, iConnect will detect the presence of IPNRouter and automatically control that software as well.
Installation is simple.
The application is distributed on a self-mounting Disk Copy disk image which can be opened with Disk Copy or Stuffit Expander. Just drag the iConnect folder from the iConnect disk to your hard drive. You may use it for up to 30 days after which you are expected to register the software. You may use the provided Registration application to register by mail, fax, or email. After registering, you will receive a serial number.
