#nmap -sS -p 0-65535 x.x.x.x
Interesting ports on w.w.w.w (x.x.x.x):
Not shown: 65522 closed ports
PORT STATE SERVICE
21/tcp open ftp
22/tcp open ssh
111/tcp open rpcbind
411/tcp open rmt
1080/tcp open socks
4661/tcp open unknown
Nmap finished: 1 IP address (1 host up) scanned in 3.888 seconds
Where x.x.x would be a IP accross your filtered
network(that would not be hard to setup).
Nmap will report the state of the ports,i.e
if they are open ,closed or filtered.
you should see the nmap man page for different
kinds of scan.
Also as to see where exactly the outgoing packets
are blocked you can use a technique described
below
