If you are using RHEL (Redhat), Fedora core or Cent os Linux just type following commands to disable the iptables firewall:
# service iptables save
# service iptables stop
# chkconfig iptables off
If you are using any other Linux distribution type the following command to clear up IPv4 based firewall rules:
# iptables -F
# iptables -X
# iptables -t nat -F
# iptables -t nat -X
# iptables -t mangle -F

# iptables -P INPUT ACCEPT
# iptables -P OUTPUT ACCEPT
You may need to put above rules in a shell script and execute the same. Also remove your iptables startup script from your network configuration file such as /etc/network/interfaces. Look for post-up directive.

Is there a way I can make some sort of bridge connection and if not, were do I type in this code
Simple and useful article! Now I understand how to disable iptables :-)… How is it possible to disable iptables in other distributions? Does the “service iptables stop” command work?
thanks
It seems not that effective. When I restart server iptables will be up again!
Can I just de-install (remove) iptables ?
it doesn’t work for me on Centos 7 :
But on every reboot everything comes back as default or something and ftp along with webmin are blocked! I hate this shit :)
systemctl disable firewalld
systemctl stop firewalld
