iptables - bad rule

Guest Four20

Recommended Posts

Ok, i just set up a linux box with my old machine since I built a new one.


I set it up and its all running good with internet hooked straight to it.

I go and hook the internet back to my newer machine. hook the two computers together via cross over cat5 cable and start it up.

I get the error

iptables - bad rule - does a matching rule already exist


There are 5 lines at the top that end with "accept"

and about 6 at the bottom that say "reject"


can anyone help me with this issue. I shared my internet on my windows machine. But the linux box isnt recognizing on the network.


any suggestions will be most appriciated.

if its redhat, try running lokkit and disabling the firewall temporarily


does that work ?


does the machine get an ip ?


(ifconfig as root will tell you)
