Throttling IPv6 connections?

[BenoitZugmeyer]

First, thank you for this project, it is super useful.

On macOS, it seems that throttle works for IPv4 connections, but not IPv6:

$ throttle --up 330 --down 780 --rtt 200
Started throttler: Down:780kbit/s Up:330kbit/s RTT:200ms PacketLoss:0%

$ curl -4 -i 'https://freetestdata.com/wp-content/uploads/2022/02/Free_Test_Data_2.48MB_AVI.avi' --output /dev/null 
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  4 2548k    4  115k    0     0  58873      0  0:00:44  0:00:02  0:00:42 58877^C

$ curl -6 -i 'https://freetestdata.com/wp-content/uploads/2022/02/Free_Test_Data_2.48MB_AVI.avi' --output /dev/null
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 2548k  100 2548k    0     0  18.4M      0 --:--:-- --:--:-- --:--:-- 18.4M

I wonder if IPv6 can be supported too? Or at least, have a word in the documentation?

Note: I used it to debug a Node.js script, and since Node 16, I needed to use --dns-result-order=ipv4first for using IPv4 over IPv6, so the connection can be throttled.

Hi @BenoitZugmeyer sorry for the late answer. I wonder maybe we need to setup the rules differently? Any chance you have the time to take a look? The easiest way to see what commands that runs is:
LOG_THROTTLE=true throttle cable

And the check for documentation for dummy net.
