Hello,
I am a new user of the Simple Port Tester, and I want to ensure I understand how the Simple Port Tester works.
I set the IP address to the only physical connection located on my PC. I then scanned ports 22, 23, 80, and 8080. I also was performing a Wireshark capture. All the ports failed (as expected), but I wanted to ensure the tool was operating correctly.
1) While the port scanning was happening, I was observing the firewall logs. I saw IP address 208.113.208.159 attempting to communicate with my router's IP address on ports 22, 23, 80, 8080.
2) After analyzing the Wireshark capture, I observed that my PC was communicating to IP address 205.196.208.221 on port 80 (http). The TCP stream showed that my PC was communicating to Host:
www.pcwintech.com and was issuing the following GET request:
/port_test2.php?result=test&port=22 HTTP/1.1
Questions:
1. Why are 2 different IP addresses used (208.113.208.159 and 205.196.208.221)?
2. Is the below procedure the correct process of what is happening when using the port tester tool?
a. PC running Port Tester tool communicates to PC-WinTech server to inform what TCP/UDP port to use. Information is sent within http (port 80 or 8080)
b. PC-WinTech server tries to open the specified port by communicating to the far-end router
