IPtables wiki

Hi,

I followed this wiki.

https://wiki.archlinux.org/index.php/Si … l_firewall

but here I get this message error

Note: NEW but not SYN is the only invalid TCP flag not covered by the INVALID state. The reason is because they are rarely malicious packets, and they should not just be dropped. Instead, we simply do not accept them, so they are rejected with a TCP RST by the next rule.

iptables -A INPUT -p udp -m conntrack --ctstate NEW -j UDP

iptables v1.4.21: Couldn't load target `UDP':No such file or directory

Try `iptables -h' or 'iptables --help' for more information.

Can you help me ?

Thanks,

Dominique,

Re: IPtables wiki

Post the output of `iptables -nvL` and edit the title of your post to be more accurate.
