admin All of us have problems sometimes with DHCP, especially if we use the Fortigate it as a DHCP relay server.
The following commands are used to best troubleshoot the DHCP process:
#diag debug en
#diag debug console timestamp en
The following is used if we use IPSec DHCP relay
#diag debug app dhcprelay 7
The following is used if we are using IPsec DHCP Server
#diag debug app dhcps 7

Logging and Alerts
Fortigate can store its logs in the following:
1. Local HDD – this option can be enabled from the CLI
2. FortiAnalyzer – this is my favorite. It is a device to which Fortigate sends all the logs and then you can create pretty reports.
This option can be enabled by providing the IP of the FortiAnalyzer(FA) or by using “Automatic Discovery”, but for the automatic discovery you will need to have the FA in the same subnet as the Fortigate.

Fortigate AntiVirus and AntiSpam
As we all know Fortigate provides a lot a features for only one device.
Let’s see how some of them work:
I. AntiVirus
This tool scans the traffic and applies the following rules:
1. File size – if a file is large that what you define, then this gets dropped
2. File pattern – if a file matches a pattern, it get dropped
3. Virus scan – it scans a file for virus, if it gets a positive then it gets dropped
4. Grayware – scans for grayware programs
5. Heuristic – scans with an heuristic algorithm
6. File type – you can define some types that gets dropped
II. AntiSpam

Fortigate Tutorial 3 – Default Protection Profiles
So you just started using your Fortigate and got the hang of it. You found out that it has some default Protection Profiles.
This tutorial will help you explain the Default Profiles that Fortinet sent its powerful firewall.
1. Strict
This profile applies default protection profiles for HTTP, FTP, IMAP, POP3, SMTP traffic
This protection profile is not normally used since it is to “harsh”
2. Scan
This one is good for virus scanning for the following network traffic: HTTP, FTP, IMAP, POP3 and SMTP traffic.
If your FG has a HDD then if this protection profile catches a virus it will automatically quarantine it.
3. Web
The Web protection profile applies virus scanning and web content blocking to HTTP traffic. This one is the one to use in case you do not define it yourself (as i do 
).
4. Unfiltered
This is pointless. It doesn’t scan or block anything.
Hope this tutorial helped you.
Thank you,
Daniel

Fortigate Tutorial 1 – Firewall Default Settings
You just bought a Fortigate? I want to tell you from the beginning GREAT PICK!
Much easier to use than the Cisco ASA and a more friendly GUI then ASDM.
So now you added your Fortigate(maybe 50B like in the pic) to the network and you do not know where to go next?
Here are the default settings for almost all of the Fortigate Firewall:
Internal: 192.168.1.99
WAN1: 192.168.100.99
WAN2: 192.168.101.99
DHCP is enabled by default on the internal interface with the following scope: 192.168.1.110 till 192.168.1.210
Default username: Admin
Default password: <none>
Now you can connect to the firewall with SSH on port 22 and go from there.
Hope you enjoy the Fortigates as much as i do.
See you in the next tutorial!
