Bug 282154: devel/py-twisted: 24.7.0 breaks EPSV
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=282154



--- Description ---
It looks like the update to 24.7.0 breaks EPSV.

This was discovered because the pf proxy:ftp test started failing:
https://ci.freebsd.org/job/FreeBSD-main-amd64-test/25597/testReport/sys.netpfil
.pf/proxy/ftp/

I've confirmed this isn't a pf issue, both by reverting freebsd to a version
from February (which still fails this test, but didn't at the time), and by
running a very simple setup without pf loaded, `twistd -n --logfile=-ftp -r
/tmp -p 21` and `ftp -a 127.0.0.1` (with ‘get file’).

Disabling EPSV (by using 'epsv' in the ftp client) allows the transfer to
succeed.

Without that I see:
> 229 Entering Extended Passive Mode (|||46490|).
> ftp: Can't connect to `127.0.0.1:46490': Connection refused

It looks like twistd was listening on a different port for the data connection.
