Depending on is your broadband provider on board the yacht they most likely have the "port" closed on the VSAT router. This is a typical practice on board yachts due to Skype requiring such a large amount of bandwidth. If the yacht is equipped with a VSAT then the NOC "Network Operation Center" would be able to tell you if they are blocking the port or not. If they show it opened then the Local Area Network ROUTER on board the yacht will most likely have the port blocked. In this case you need to speak with your network administrator (most of the times it's either the captain or the engineer) to see if they will open it up for you. Good luck
