LogMeIn is one of the remote control tools like GoToMyPC that is a real boon to supporting your own computers remotely and other people's computers too. But with the increasing security consciousness, we use firewalls to block misbehavior of others. Once LogMeIn is installed on the client computer (the computer that will be remotely controlled), it should set its required firewall port open but it doesn't.

Here's what to do and it differs slightly for the different firewall products out there.

Port 2002 needs to be open for TCP inbound and outbound traffic.

A port is a connection your computer makes with another computer. Traffic is sent and/or received on that port. Ports are numbered from 1 to 65535 and you as a user of your compuer would normally not have to be involved with this. You would normally install your anti-virus software, or your firewall software or whatever protection you might have, and hope that all software that you install would just work with the firewall. Well, it doesn't.

 I will post additional instructions for a variety of packages later, for now, this is the answer to why LogMeIn does not connect properly to some remote computers.
