Depending on your kernel version this may be relevant: https://www.spinics.net/lists/netfilter-devel/msg55682.html (linked from https://askubuntu.com/questions/1059781/ufw-allows-22-for-ipv4-and-ipv6-but-ssh-disconnects-when-enabling) Our environments are using Ubuntu Bionic with a 5.0 kernel and we are still encountering this issue, variously with winbind and ssh. Although the email thread discusses ssh I understand the issue is relevant to any TCP connection.
