hi list,

i wonder whether anybody run into this scenario before and has a hint=20
how to resolve it...

my DrayTek Vigor 2200W router mangles UDP-based traceroute, i.e. the=20
only hop that is listed is the router/gateway itself -- then it gets=20
pitch black :(

when running =B4traceroute -I bla.foo.bar' (thus forcing traceroute to=20=

request ICMP echo replies) all works well.

but this is not the problem since i can put traceroute the options i=20
want it to get. xtraceroute is the problem because it *always' runs the=20=

UDP-way of tracerouting... and thus gets no useful information.

anybody with a nice idea how to solve this?

tia & cheers,

timo=
