How to use Netfilter properly with IPv6?
Hello,
on a PC with Debian 8 I try to use a Bash script with Netfilter rules so that only traffic goes in and out that is wanted. For that I set all 3 default policies to "drop". The machine uses DHCP to get its IP, gateway and DNS. And I never checked so I was quite surprised that my router/modem assings an IPv6 and not only an IPv4. I wonder if I need additional rules for IPv6. Could somebody explain that problem to me?
Greetings,
SInt

Hi everyone, I would like to allow multi users to access P2P networks, so I wonder if there's a way to tracking these kind of protocols with netfilter, and also compatibility with nat, like the module conntrack_ftp seems to do with the FTP protocol.
Thanks guys. (0 Replies)
