Hi,

There are no such feature or product in Azure to block torrent traffic. But most torrent traffic uses TCP and UDP ports in the range of 6881-6889 and sometimes higher. Blocking these ports can significantly reduce the torrent traffic.

So you can use the NSG to block traffic that is sent in over these ports.

@msrini-MSFT how i can inform admins if the torrent is active, or active torrent traffic usage in networks? I have read in the blog that torrents can use any high port.

You can have a deny all ports incoming to your VM and allow only the ports that you are using.

@msrini-MSFT should I block outbounds ports?

Not required. You need to block the inbound torrent traffic hitting your VM.

@msrini-MSFT are there possible to block all vNet? My VPN clients located in the same vNet as the VM

Yes, you can have deny all (which includes the VNETs )and then you can allow specific IPs and ports on top of that.
