If you wish to change your firewall settings you need to log into it and make sure the correct ports are opened and that uPnP is enabled.
Type the model of your firewall/router into google with manual after it and you should be able to get the manual up which will then give you directions on how to log in and make changes to your firewall.
Go careful though, if you dont know what you are doing or it's not your firewall/router then ask whoever set it up for help.
