One of my computeer with IP 10.10.11.152 got ping timeout to its gateway fortigate firewall internal interface with IP 10.10.11.1. How ever other servers on the subnet like 10.10.11.150 can ping 10.10.11.1. When I did ping capture on the firewall, I can see the following outputs. The replied packets are not going through internal inteface, but from root interface, but I have never created any interface called root. It's so confusing. Anyone has ever seen this crazy behavior before. Any solution to fix this issue? thank you
