A network administrator connects his PC to the INTERNAL interface on a FortiGate unit. The administrator attempts to make an HTTPS connection to the
FortiGate unit on the VLAN1 interface at the IP address of 10.0.1.1, but gets no connectivity.
The following troubleshooting commands are executed from the CLI: user1 # get system interface
== [ internal ]
namE. internal modE. static ip: 10.0.1.254 255.255.255.128 status: up netbios-forwarD. disable typE. physical mtu-overridE. disable
== [ vlan1 ]
namE. vlan1 modE. static ip: 10.0.1.1 255.255.255.128 status: up netb ios-forwarD. disable typE. vlan mtu-overridE. disable user1 # get router info routing-table all
