firewall yes or no can ports be opened

[firebyrd10]

I've been searching through the forum with so far no helpful answers.

Is there a firewall inplace on the live cd version 3.3 of knoppix? I want to know because I like to be an Ultrapeer in in gnuetlle (is that how you spell it) network and while on knoppix I can't run bearshare so I downloaded Limewire anyway I set the ports to forward to my IP address (I manually set it) and waited all night in hopes of becoming an Ultrapeer. I know the option to become one isn't turned off and by now I would have become one normally so my guess is there is a firewall blocking LimeWire's port (6346) I know it must be knoppix in someway because on Windows I can connect just fine (I use the same IP on knoppix as in windows)

Now then if there is a firewall how do I open a port and/or disable it?

There is no firewall on the Knoppix CD when running all ports should be closed by default unless you open them up. Go to Arno's and get the iptables firewall script. Set it up according to the instructions and in the /etc/iptables-firewall.conf set these if you need both the TCP and UDP ports open and NATed then start the firewall.

NAT_TCP_FORWARD="6346>192.168.0.1"
NAT_UDP_FORWARD="6346>192.168.0.1"

Change the 192.168.0.1 to the address being forwarded too if you only need the ports open on the firewall machine then use these.

OPEN_TCP=6346""
OPEN_UDP="6346"
OPEN_IP=""
OPEN_ICMP=0
