The issue is that no traceroute ever completes successfully: traceroute 209.191.118.103 traceroute to 209.191.118.103 (209.191.118.103), 64 hops max, 40 byte packets 1 * * * 2 * * * 3 * * * 4 * * * I also tried traceroute -e 209.191.118.103. Same result. Our Dlink router has these two enabled: ping-outbound ICMP: Echo (Ping) Return ICMP Errors ping-inbound ICMP: Echo (Ping) No host responds to traceroute commands.
