Bad argument `5666'

Hello,

When I type this command:
Code:
iptables -I RH-Firewall-1-INPUT -p tcp -m tcp -dport 5666 -j ACCEPT

it returns me :
Code:
Bad argument `5666' 
Try `iptables -h' or `iptables --help' for more information.

The rule works for me.

What is that strange hyphen thing preceding the destination port? it's not a regular hyphen (that option takes two hyphens)

It looks like you did not create the chain (-N) before?
