Since Linux uses UDP for trace-routes, this can originate from a –reject-with icmp-host-prohibited rule in the destination host’s firewall. Some Linux distros have this as a default configuration. To fix this you need to reply with –reject-with icmp-port-unreachable on UDP ports 33434 through 33534 instead.<\/p>\n
