I would have to find another program that allows the use of the other packet type. Seems like my ISP disabled the type of packets used in Windows tracert. When I had cygwin installed, I could use it with the right options.
Might be my ISP's DNS server hiccuping. Sometimes I've had to use an alternate server. The ISP likes to place an add up when the DNS that you type in is invalid.
The hiccup has only been with ETO, though so that, as you point out, could be a gateway along the route.
