Hi, Assuming that you are inside the network of the NAT gateway, you can use nmap to find out what IS blocked. A single 'nmap <target>' should show you what is 'filtered'. You can test what is not blocked using individual ports, such like: # nmap -P0 -sS -p 6667 --packet_trace <targets> -- Vinicius

be sure. How can I use nmap to find what ISN'T blocked? _______________________________________________ firewall-wizards mailing list firewall-wizards () honor icsalabs com http://honor.icsalabs.com/mailman/listinfo/firewall-wizards
