Nov 26, 2013 · Step 1: My Source address will make a packet with destination ip address of 8.8.8.8 and a destination port number Step 2: Of course my packet will reach my gateway server. On seeing receiving the packet my gateway server will reduce Step 3: On receiving this TTL Time exceeded message, my Apr 16, 2017 · traceroute still not working for 1909 tracert.exe works in a command/powershell window, but traceroute does not work in Ubuntu under WSL Traceroute on the other hand sends ICMP packets with increasing TTLs so each L3 device along the path has to send a response to source IP. So it could be acls, firewalls, router configurations etc. that are stopping the traceroute from working correctly. Re: PING work TRACEROUTE NOT !!!!! on ASA Even if ICPM can be inspected and you can ping to the internet but when you do a trace to the same IP as you ping the firewall will block the returning traffic, I had the same problem until I allow icmp from any to the internal IPs as traffic hit the outside interface then everything worked. In the modern network environment the traditional traceroute methods can not be always applicable, because of widespread use of firewalls. Such firewalls filter the "unlikely" UDP ports, or even ICMP echoes. To solve this, some additional tracerouting methods are implemented (including tcp), see LIST OF AVAILABLE METHODS below.

Probably, either the router has a configuration problem, or the 22.110.0.0 network does not exist, reflecting a bad IP address. Jul 05, 2017 · Traceroute shows us the path traffic takes to reach the website. It also displays the delays that occur at each stop.
