PORT FORWARD UTILITY SAYS PORT OPEN SOFTWARE

Port 500 for Internet Security Association and Key Management Protocol (ISAKMP).

Port 445 for Server Message Block (SMB).

Port 161 for Simple Network Management Protocol (SNMP).

Port 143 for Internet Message Access Protocol (IMAP).

Port 123 for Network Time Protocol (NTP).

Port 110 for Post Office Protocol, version 3 (POP3).

Port 80 for Hypertext Transfer Protocol (HTTP).

Port 25 for Simple Mail Transfer Protocol (SMTP).

Ports 20 and 21 for File Transfer Protocol (FTP).

But some widely used ports and their associated networking protocols are TCP and UDP headers indicate the port number to which network traffic is forwarded. The IP(Internet Protocol) address enables network communication on a specific device, and the port numbers specify the particular service to target on those devices. For example, all Hypertext Transfer Protocol (HTTP) messages go to port 80.

Mostly each port is reserved for serving a specific protocol.

TCP (Transmission Control Protocol) portsĪ number is assigned to each port, so the ports are standardized and adopted across all the network-connected devices.

There are two types of network ports on each computer.

Each network request contains the port, IP address, and the network protocol to complete the request's destination network address. The incoming packet's headers define which port it should be forwarded. The email traffic lands on a different port (port 25), and web traffic lands on a different (port 80) even though both reach the computer over the same network connection. Ports facilitate computers to differentiate among different kinds of traffic.

We can recognize it as a logical construct used to specify a network service or a particular function at the software level. Each port is associated with a specific service or process. Ports are software-based and managed by the computer's operating system. It is the virtual point where the network connection starts and ends. Port is a term used in computer networking. About Online Port Scanning - Discover Open TCP & UDP Ports What is a Port?.

I disabled all firewalls and protectors, etc, unless there is something in the modem I missed. TL DR: Something is blocking my open ports. When I turn IP Passthrough off and scan a port like 80, it comes back as a timed out. Now any port I scan is "connection refused", I am assuming because it works like a DMZ and opened all of them. All the same result - "connection refused".ģ2657 Refused (When opened specifically, they get refused.)Ĭlosed/Random Port 3277 Timed Out (This is to show that normally, ports simply time out if unopened.)ĮDIT: I tried IP passthrough on Default Server instead of off, and defined my device in the address box. PS: For the record, I've tried other ports as well. I've never had an issue forwarding ports in the 10+ years I've been using the internet. If any of you have had any experience with this ridiculous problem, let me know. I'm interested in being able to open my ports when I pay for internet, just as I've always been able to do. I've attempted to call ATT about this, and they refer me to some fee-based service that is far too expensive. I tried to use your port tool regardless, but it makes me login to the ATT website in an endless loop. ( For any of you ATT techs, my IP begins with 108, not 10. Nobody can connect to me via that port, even after opening it in the modem. When I scan a port I opened via the modem, it says "connection refused". I scan a closed port with - it says connection timed out, expectedly. I save it, apply it, and it appears in the list set for my device. I've disabled every Firewall option on the modem, as well as my computer. I forward the ports 32657 to 32659, on both UDP and TCP. I make sure it's on the correct device (my device). I go into my Motorola NVG510, head to NAT/Gaming, and forward some ports.
