This generally isnt a big deal because routers (and Linux routers) generally take this just fine. The Linksys devices block these UDP datagrams for some reason (security?) so to traceroute out, use the -I option (read the man page for more info) I have also heard that if you force the UDP port down to port 7 it will work for some linksys devices (depending on revision).
