hi,

issue:

ping to gw does not work , but hw address is visible on the Switch

Fortigate 60d, Version 5

1. switched Fortigate to interface

config system global     set fgd-alert-subscription advisory latest-threat     set hostname "FGT60D4614027069"     set internal-switch-mode interface     set timezone 04 end

2. defined Interface "internal1"

edit "internal1"         set vdom "root"         set ip 10.86.249.38 255.255.255.240         set allowaccess ping https http telnet         set type physical         set description "inside"         set snmp-index 1     next
