Perhaps firewalk will solve that question? I'm not sure I completely understood the problem, but if you're having a firewall/router in front of a network and wants to map the firewall's rulebase than perhaps firewalk could help. But you will have to know a host on the inside network of the filtering devices. The method will only work at level 3 firewalls/filtering devices. You let firewalk calculate the TTL so that TTL is 1 when you get to the firewall/router/filtering device. If the firewall is letting the traffic through, the TTL will reach 0 and a ICMP message is returned. If the fw is not letting the traffic through, the packet is simply dropped. / Alex 2009/11/5 Phunkodelic <phunkodelic () gmail com>:
Looking for a way to find out who or what device is blocking traffic on a specific port. Sort of like a trace route tool where you could designate the port to test with (UDP/TCP). I realize that UDP may be hard to do since it is a connectionsless protocol. Anybody?
