Bret is having issues accessing wireless cameras due to blocked ports on his router. Leo says what he wants to do is "port forwarding," and it may be that he'll want to use a higher, five digit port to connect to them. The lower port numbers may either be reserved or in use, like 8080. He should try going higher. He'll also need to use ports that his devices understand. So Bret should look in his manual to see what ports the device supports.
