could you tell me how to find out all the firewalls that are installed on my system Ubuntu 10.04 and on external hardware and which of them is blocking port 80?
thank you

To view the firewall configuration on your localhost, run 'sudo iptables -L'. If you have no control over your upstream firewalls, you will have limited ability to probe or change them. You should talk to your system/network administrator or ISP.
