      Firewall Rules

      I am just checking that my current firewall settings are correct. Is it ok to have my outbound services ALLOW always?

      I take it the router only blocks incoming hackers, trojans etc, but it doesn't stop information leaking out (outgoing)

      Sorry to sound simple but I didn't want to change anything as I am not an advanced user

      These are the settings I have, is my router/broadband at risk, or do they need to be changed.

      Default Yes Any ALLOW always Any Any Never
      Inbound Services
      # Enable Service Name Action LAN Server IP address WAN Users Log
      Default Yes Any BLOCK always Any Any Never

      In the work environment this is normally set to no and the Network administrator has to open each and every port that is required for the business to work. There will be some which are already open, but most will be closed.

      This means that they have the power to enable ports so that Skype can work, or to allow people to play their Xbox at work.

      In the home environment things are a little different. Most people have no idea what each port is normally used for and the last thing most want to do is adjust their router so that they can make a Video call to a friend or relative.

      Yes I know that some more advanced routers aimed at the home market have features to enable/disable these, but the Sky router is targeted at a range of people who will include those who have no knowledge of the technical side of computers.

      If you have a service which you wish to prohibit, then you can do so here.

      As for trojans or viruses, they are going to be a little more clever. It is likely that they would use a frequently used port (i.e. 80) so that their traffic will pass through as many routers as possible. I am not someone who has delved into this so I do not have the knowledge to confirm if this is 100% true though.

      In a word NO. Outbound ports must always be open to allow communication with the internet. There are exceptions where you want to block access on a particular device. eg. Stop children accessing the internet after a certain time, but unless you have kids there is no need to worry. Inbound ports should only be opened for a specific purpose. You can read more on this in this article. - router - What is port forwarding and what is it used for? - Super User
