Temat: connection was aborted by the software in your host machine
most sites use passive mode as it does not depend much on the users configuration - namely the router config. that site, however, has disabled passive mode and you need to use active mode. you should try to enable upnp (universal plug and play) on your router first. if that doesn't work, you have to manually forward router ports, which is a bit more work, but is documented very well (just google for: "your router name" port forwarding).
