iptables failed with " iptables v1.4.21: Couldn't load match `-d':No such file or directory" message

Question

I am running kernel 3.14.18 and using iptables 1.4.21, built with these options --static-enable --disable-shared.

When I run this command:

/sbin/iptables -A PREROUTING  -m -d 127.3.0.2/24 -j DNAT --to-destination 10.0.0.1 -p udp -dport 69

I get this error message:

iptables v1.4.21: Couldn't load match `-d':No such file or directory

Can anyone help explain what I am missing?

Answer 1

I know this is an old post, but for others who come across this via searches....

The -m option is to specify a module to load. Correcting this and the --dport vs -dport mentioned by Augusto you may want.

/sbin/iptables -A PREROUTING -m udp -d 127.3.0.2/24 -j DNAT --to-destination 10.0.0.1 -p udp --dport 69

Answer 2

Try --dport instead -dport (missing one -)
