this page you can check network ports to see if they are open or closed.
Country: United States
ISP: || *.compute-1.amazonaws.com
Operating System: Not automatically detected. 32-bit |
If the ports are open then it is
likely that the ISP or internet service provider has opened them, or that port
forwarding has been configured on the router, modem or firewall.
If they are closed then you cannot communicate with any services that might be
running internally from the outside. You will either have to configure the network
equipment or work with the originating ISP to open the ports you need.
Perhaps you don't need any ports to be open, then you can use the tool on this
page to test your network security.
