Thread: Firewall issues

I am using a computer that is a part of a LAN. Now I need to know whether the LAN firewalls a particular port or not. Instead of runnning everytime to the network administrator can I know how do know this on my own?
Thanks in advance.
One way is to run the 'nmap' command (available in most Linux distributions) from a PC outside your LAN, giving it the address of your PC inside the LAN, or of the gateway itself. You usually get different responses to ports with no servers and ports that are blocked.
