Yes. I did "sudo apt-get install iptables" to be sure. It seems like there is another package that adds the iptables-legacy links. I even removed and installed fresh wsl. Either Windows is remembering somewhere that it doesn't add the iptables-legacy rules, or I'm missing a package (or more than one) somewhere.
$ dpkg -S /usr/sbin/iptables-legacy
dpkg-query: no path found matching pattern /usr/sbin/iptables-legacy
$ iptables --version
iptables v1.6.0
I think iptables installs when Debian itself is installed. It just isn't setting up the legacy rules. Searching around google, the answer that keeps popping up is to use the update-alternatives, which is the whole problem

I agree it must be something in iptables too. It just doesn't set the default links in the install process to be able to switch to the legacy rules.
Debian 9, I see. I honestly haven't tried this with older versions of Debian. Did 9 even use nftables? Pretty sure there is no legacy version because iptables wasn't legacy then. Does dockerd work?
I didn't notice the 9. It is the latest from Microsoft - or so I thought. Dockerd does work. Maybe the project I'm trying to compile doesn't like Debian 9! Here I thought it was because the iptables didn't follow the instructions. Strange my Debian is so far behind.

Just double-checking: are you sure you have
iptables
installed?Yes. I did "sudo apt-get install iptables" to be sure. It seems like there is another package that adds the iptables-legacy links. I even removed and installed fresh wsl. Either Windows is remembering somewhere that it doesn't add the iptables-legacy rules, or I'm missing a package (or more than one) somewhere.
Well, let's check. On your Debian install, what is the result of
dpkg -S /usr/sbin/iptables-legacy
?dpkg shows:
$ dpkg -S /usr/sbin/iptables-legacy
dpkg-query: no path found matching pattern /usr/sbin/iptables-legacy
iptables is installed:
$ iptables --version
iptables v1.6.0
I'm not sure what happened to the previous reply:
$ dpkg -S /usr/sbin/iptables-legacy
dpkg-query: no path found matching pattern /usr/sbin/iptables-legacy
$ iptables --version
iptables v1.6.0

I probably sound like I am quite fixated on the iptables package, but would you try reinstalling it? Using apt install --reinstall iptables
So I looked in /usr/sbin... I only have one entry if I look for iptables:
$ ls /usr/sbin/iptable*
/usr/sbin/iptables-apply
I believe there should be nearly a dozen links to other objects there.
$ sudo apt install --reinstall iptables
