Strange behaviour with compiled version! 🤔🤔🤔

[verbal666]

Hi all.
I have a strange issue with the compiled version of redsocks, both inside ad AlmaLinux and Ubuntu.

PRETTY_NAME="Ubuntu 24.04.1 LTS"

• same redsocks.conf
• same iptable nat table

APT STANDARD PACKAGE [/usr/sbin/redsocks -c /etc/redsocks.conf] [OK]
/usr/sbin/redsocks -v
redsocks/0.5
