Hi all, I have encountered the following problem: I set up a slightly modified ipfw ruleset with a default deny, based on the "simple" ruleset from rc.firewall and opened udp port 33434 (the default source port for traceroute I thought). To my surprise I was not able to run a traceroute through it - the packets were always denied. Examining the logs I found out that traceroute did not use a specific source port for the outgoing queries. Even when I invoked traceroute with -P UPD and -p 33434 the source port was >35000. Each invocation incremented the port no. by one. What am I missing? I suppose I did not quite understand the way traceroute works - any suggestions are welcome. Cheers, Thomas Seck P.S: Please cc me or the list as I am not subscribed to -questions.
