How To Test If My Isp Is Port Filtering
How to check if the isp is filtering/blocking the ports?
Hello,
A friend of mine connected his iphone to the pc directly using the usb and he tethered the connection.
A game named red dead online is constantly disconnecting him from the game server. I cerise somewhere on the net that the issues has been acquired by the ISPs that probably are blocking the ports, because the cellular connexion does not have a pubblic IPs but only a individual ones...so the port cannot be mapped due to this reason.
And so I decided to create on my pc a similar configuration connecting the Iphone to the pc and tethering the connection.
I was using resource monitor and portqry to sympathise if the ISP was blocking some ports causing the problem, and I made a session connecting my pc to some other ane using anydesk. Frankly speaking there aren't any issues with the connections, of course there is some differences in the used ports and IPs (in comparison to the cobweb connections). Probably I am not agreement how these two application works correctly, but how to understand if the ports are blocked?
Practise I demand to utilize other applications to check this outcome?

I am not certain how much these websites works in the right way.
That site is for inbound connections. So if you didn't have some service listening locally on that port you would not go success. If you lot wanted to check outbound and so from PowerShell (using some ip accost / port combination)
Test-NetConnection -ComputerName "192.10.34.99" -Port 999 -InformationLevel "Detailed" --please don't forget to upvote and Accept equally answer if the answer is helpful--
I have had luck with https://www.wireshark.org/ it takes a bit of setup, configuration, but you tin filter down to IPs. It will capture All network traffic on the adapter and show you failed connections and which ports/protocols are beingness used.

Hello,
I am non certain how much these websites works in the right manner. Now in this moment I fabricated a test. I connected the local pc to my home pc using Anydesk and with resource monitor I checked the agile TCP connections established with Anydesk. I take the local port of Anydesk which connects my dwelling house pc and I put it on the given website by you lot. Information technology returned me the error: I could not run across your service on (xxxx) on port (xxxx)...if information technology is truthful why there is a communication on the port that has been shown in resource monitor?
