You may wish to open some or all of the ports on your firewall depending on your situation. Some routers do not allow allot of pinholes and may crash or reboot repeatedly, if this occurs contact your router maker for updated firmware. You do not need to open all of these ports only the ones you use. There are 2 types of firewalls, software and hardware. You may have to open these ports and properly forward them in all devices and programs. Many situations have 1 or more hardware firewalls and a software firewall. If after opening these ports you still have issues try placing your system in to the DMZ of the firewall and see if the issue resolves. It is recommended to open only the ports needed as opening to0 many could put you at risk of attack.
