Hi: I'm using 4.7p1 here, and I've had all sorts of fun on occasion with traceroute and my various firewall/routers. The default traceroute will not work since UDP traffic is apparently blocked on the return. Opening up port ranges on my router just doesn't seem right. However, Linux traceroute has a -I option (I think Windows tracert uses ICMP ECHO by default) which allows it to work through a home firewall router. The FreeBSD port for mtr also works. Is there anyone who has considered adding this capability to FreeBSD? Thanks, -Clint
