Hi Arun,
Thank you for applying the patch, I think it’s much better. Truthfully i am relieved that you are an iptables newbie and so am I!
I think there could still be some work done to this recommendation. For example, when I use this updated iptables firewall selection, I am unable to telnet into ports open on localhost. An example is that I am a heavy user of VNC/SSH tunnel connections and it doesn’t let me do that, it blocks e.g. port 5902. (A similar naive rule in nftables does let this work!!!)
But so many examples are given in iptables (esp. WireGuard stuff) and so if you have no objections, I would like to take a further look and maybe even ask around as to what the ‘ufw allow ssh’ behavior vis-a-vis iptables best practices.
Best regards,
Eric
