Re: Traceroute not showing hop
Please provide the following information to investigate the issue further:
1) A diagram of your topology.
2) On Fortigate's CLI, run the following command:
diagnose sniffer packet [interface you are trying to traceroute to] "(host <router's ip address> and host <fortigate's ip address>) and icmp" 4
At the same time, run traceroute on the cisco router for at least 6 hops and advise results.
3) What firewall policies do you have in place that match inbound traffic? Is logging enabled on them and if so, what do the logs show?
