Re: [Speed] Is this odd.. 2nd hop of trace showing 100% packet l

We're not blocking ICMP to that hop. You can test this by pinging your gateway IP. The gateway IP is on the same virtual interface of the CMTS so if you can ping your gateway but not the private IP then that proves that we're not blocking pings.

When tracing, the primary IP of that virtual interface is what responds. This primary IP is a private IP within RFC1918. Many devices do not allow private subnets on a WAN interface or may see the chatter from that private IP and block it.

So long as the hops past hop 2 do not show packet-loss then hop 2 not responding is not a problem. However, if you wish to test packet-loss to hop 2 then simply run pings to your gateway IP.

I'm not exactly sure if it's being tired, but this just confused the hell out of me for the longest, LMAO
