Re: Setting ICMP/UDP Virtual Session Timeout
Welcome to the Fortinet Forum.
I am not sure what exactly the PCI report is referring to.
However, on the Fortigate, both the UDP idle timer and ICMP ttl are different from the session-ttl.
For UDP, below takes effect:
config sys global
set udp-idle-timer 180
And ICMP, by default, it is 60 seconds ttl.
Hope that helps
