Sorry CyberT,I did misunderstand
I would ask the ISP if they know of any alternatives.Most of the so-called "Visual" or "Graphical" ping or traceroute utilities are just frontends that use your default tcp/ip utilities.
I did a search for alternatives but could only find the above.I even tried a search for non-ICMP alternatives but didnt get(or expect)any results.
Seems like this ISP wants no one being able to send ICMP packets except themselves.
