OK guys, I have a customer complaining that he has several problems during the day with the Comcast connection getting really slow, and some times no connection at all.
I went to the job site and saw that happening, so I decide to do a Traceroute to determine where the problem was since Comcast told my customer that was not on their end.
I took a screen shot of the Traceroute while the connection was normal, and when there was an issue that you can see below, but there is something that I need an explanation for, and it is that second hop timing out on both scenarios.

Could someone tell me what is that time out on the second hoop of the Traceroute?
This is a Mikrotik router connected to a Comcast modem.
The first hop is the connection between the Tik and the Modem. I’m assuming that the 2nd hop timing out is some sort of Firewall at the modem, but I’m not sure.
Hi,
Yes you are right, there must be a filter on the 2nd hop. Standard traceroute sends ICMP packets to the destination but it will play around with TTL
