I'm really interested in this too!<br><br>I'm behind a Cisco 675 which uses NAT and I can't traceroute using anything (command prompt OR PingPlotter). I run an ISP remotely (about 120 miles away) and I used to use PingPlotter to keep tabs on my site. I'm really getting DESPERATE to get something to traceroute. <br><br>Any info would be greatly appreciated.<br><br>Thanks,<br>Eric Lund<br><br>
