6. Verify the DNS con
fi
gurations of the FortiGate unit and the PCs on the
internal network.
Check for DNS errors by pinging or using traceroute to connect to a domain name; for
example:
ping www.fortinet.com
ping: cannot resolve www.fre.com: Unknown host
If the name cannot be resolved, the FortiGate unit or PC cannot connect to a DNS server
and you should con
fi
rm the DNS server IP addresses are present and correct.
7. Verify the security policy con
fi
guration.
Go to
Policy > Policy > Policy
and verify that an internal -> wan1 security policy has been
added and check the
Session
column to ensure that traf

Go to
System > Network > Routing Table

reasons, including not being able to access FortiGuard. To

Security
Profiles > Web Filter > Profile
and, in the default pro
fi
le, enable
Allow Websites When
a Rating Error Occurs
.

Try pinging the default gateway IP address from a PC on the internal network.
11. Con
fi
rm that the FortiGate unit can connect to the FortiGuard network.
Once registered, the FortiGate unit obtains antivirus and application control and other
updates from the FortiGuard network. Once the FortiGate unit is on your network, you
should con
fi
rm that it can reach the FortiGuard network. The FortiGate unit must be able
to connect to the network from its management IP address. If the following tests provide
