Ubar Registered: 04/06/09 Posts: 2	I have setup ping plotter to trace an IP address 17 hops away from my router. on hope 5 I get constent errors but when I start a second instance of ping plotter and target the IP address at hop 5 shows no errors. I have also tried tracing to hop 6 during the errors and it shows no errors at 6 but does at 5. Attachments Edited by Ubar (04/06/09 06:09 AM)

That's not abnormal. When you directly ping that router, it's creating a different type of reply packet (ICMP Echo Reply), which probably has different routing rules.
