FGT VM in transparent mode on ESXi 6.0



Purpose:
Our goal with this config is to inspect/restrict traffic sourced/destined from servers on our LAN without causing much impact to the existing network.

Caution:
Failing to specify VLAN, Forwarding-domain and strict src/dst addresses may result in a Layer2 loop/broadcast storm. Please make sure to follow the directions carefully.

Topology:





1.     Deploy OVF Template
b.     I prefer to thin provision everything but that is your choice
c.     Do not power on the Virtual machine after deploying.
2.     Shut off your VM servers that you would like to add to the port group so that we may edit their port assignments.
3.     Create a Port Group in ESXi


Make sure that you assign a unique vlan id here.

Edit your server VM and assign the network adapter to your new port group.
Edit your FGTVM.
Disconnect all ports that will not be used.
You will need 3 ports: In/Out/mgmt.
In this case, we are using:
Port1 for out to our network.
Port2 for management.
Port8 for connection the VM port group.
Your port group should now look something like this if you had 2 servers in it. The only exception is that your ports are not green as we have not powered anything on yet.


4.     Power on your FGT VM  and console into FortiOS CLI.
5.     As a precaution, we should shut all ports.
config sys interface
edit port1
set status down
next
#repeat for all ports
6.     Set the box transparent mode.
config system settings
set opmode transparent
set manageip
            end
            #this will log you out so log back in.
7.     Set DNS and static route if needed.
config system dns
set primary x.x.x.x
set secondary x.x.x.x
            end
            config router static
                        edit 0
                                    set dst x.x.x.x x.x.x.x
                                    set gateway x.x.x.x
            end
           
8.     Set the forward-domain for your interfaces that are not used for management.
config system interface
edit port1
            set forward-domain 100
next
edit port8
            set forward-domain 100
end
9.     Set the allowaccess for your mgmt. interface.
config system interface
edit port2
            set allowaccess ping https
end
10.  Setup the in/out firewall policies for your Server communications.
It is very important that you set specify srcaddr/dstaddr to avoid layer2 issues on your network .
config firewall policy
edit 0
            set name “p1-p8”
            set srcintf port1
            set dstintf port8
            set srcaddr all
            set dstaddr "/32 srvIP"
            set service any
            set schedule always
            set action accept
next
edit 0
            set name “p8-p1”
            set srcintf port8
            set dstintf port1
            set dstaddr  all
            set srcaddr "/32 srvIP"
            set service any
            set schedule always
            set action accept
next     




11.  Enable your 3 interfaces on the FGTVM and power on your VM servers. Traffic towards your servers should now be routed through your FGTVM and the FGT should be accessible via the management IP.


12.  Go back and apply any UTM policies, restrict services, etc in your policies that you may require.

TCL | Create WTP-Profile and add all FAPs on units to new profile

Problem: 

We had a good percentage of access points across the enterprise that were not assigned to a WTP profile but instead were set to "Automatic". Even though this caused us no immediate harm it was definitely not optimal. 

In order to fix this issue we needed a uniform WTP profile across the board on all Fortigates and we needed to assign all of the FAPs on each FGT to the uniform WTP profile. Unfortunately, this option is not available through the standard Fortimanager features and is a very cumbersome process via the CLI because in order to reference the AP you need to address it by it's serial #.

ex:

config wireless-controller wtp
edit "FAP22B3U12345678" 
set wtp-profile "NEWdefaultwifiprof" 
end

Solution:

For a work around we will need to script out this manual process.
The script will need to:

1. Create a new standard WTP profile. 
2. Query all of the FAPs on the unit. 
3. Add each FortiAP to the new WTP profile by serial. 

Script:



#!
#creates do_cmd process
proc do_cmd {cmd} {
  puts [exec "$cmd\n" "# "]
}
#creates single instance of new wtp-profile
do_cmd "config wireless-controller wtp-profile"
do_cmd "edit NEWdefaultwifiprof"
do_cmd "config radio-1"
do_cmd "set mode ap"
do_cmd "set band 802.11n-5G"
do_cmd "set ap-bgscan enable"
do_cmd "set rogue-scan enable"
do_cmd "set frequency-handoff enable"
do_cmd "set ap-handoff enable"
do_cmd "set vaps NewSitewifi"
do_cmd "set channel 36 40 44 48 149 153 157 161 165"
do_cmd "end"
do_cmd "config radio-2"
do_cmd "set mode ap"
do_cmd "set band 802.11n"
do_cmd "set ap-bgscan enable"
do_cmd "set rogue-scan enable"
do_cmd "set frequency-handoff enable"
do_cmd "set ap-handoff enable"
do_cmd "set vaps NewSitewifi"
do_cmd "set channel 1 6 11"
do_cmd "end"
do_cmd "next"
do_cmd "end"
#queries all access points
foreach line [split [exec "show wireless-controller wtp | grep edit\n" "# "] \n] {
#regexp to match FAP serial #s
  if {[regexp {edit[ ]+"(.*)"} $line match fapid]} {
#assigns all aps on fortigate to new wtp-profile
    do_cmd "config wireless-controller wtp"
    do_cmd "edit $fapid"
    do_cmd "set wtp-profile NEWdefaultwifiprof"
    do_cmd "end"
      }

}

TCL {fortiManager} $script | grep continued

Please refer to my last post on FortiManager scripting for more info.

This script was directly inspired by the legacy Fortinet tech doc: TCL Decisions.

Below is a quick script utilizing our fairly new grep capabilities in FortiOS.

When launched this script will:

1. Find all policies that match our regex.
2. Store their "edit #" value in a variable named $policyid.
3. Run commands in a foreach loop against those policies.

















proc do_cmd {cmd} {
  puts [exec "$cmd\n" "# "]
}
foreach line [split [exec "show firewall policy | grep -f deep-inspection\n" "# "] \n] {
  if {[regexp {edit[ ]+([0-9]+)} $line match policyid]} {
    continue
  } elseif {[regexp {set[ ]+(\w+)[ ]+(.*)\r} $line match key value]} {
    lappend fw_policy($policyid) "$key $value"
  }
}
do_cmd "config firewall policy"
foreach policyid [array names fw_policy] {
    do_cmd "edit $policyid"
    do_cmd "unset deep-inspection-options"
    do_cmd "next"
}
do_cmd "end"

TCL scripting with Fortimanager 4.0

This is how you write a simple TCL that will parse the IP address from CLI and input it into your commands.

1. The Problem. 

I needed to begin logging about 200 80c's to our FortiAnalyzer.

The main issue is that all of our interface tunnels are set with 0.0.0.0 local and remote IPs for simplicity so when I input the private 192.x IP of the Analyzer into the GUI it would not route through the tunnel.

The solution to this is to use internal interface IP in the CLI like so:


config log fortianalyzer setting
set status enable
set source-ip 192.168.1.1
end

In the above example let's say that 192.168.1.1 is the internal interface IP for this box.

Now, the question was how I was going to do these for 200 units .. each with their own unique internal interface IP.





















2. Fortimanager TCL scripting

Access the Fortimanager TCL scripting feature in the "Device Manager" tab under "Tools".


Click on "Create New"


3. The Script


#!
puts "Script starts ..."

# Create do_cmd procedure to execute CLI commands
proc do_cmd {cmd} {
puts [exec "$cmd\n" "# " 15]
}

# get internal ip
do_cmd "config system interface"
do_cmd "edit internal"
set query [exec "show\n" "# "]
#puts $query
set output [split $query "\n"]
#Find IP address and puts $ip
regexp {(?:\d+\.){3}\d+} $output ip
do_cmd "end"

# set internal ip as source ip for log fortianalyzer
do_cmd "config log fortianalyzer setting"
do_cmd "set status enable"
do_cmd "set source-ip $ip"
do_cmd "end"



Input and save.


4. Execute and Verify

You can only execute scripts at the group level so (if you haven't already) create a new test script group and add your test unit into the group.

Right click the group name and select "Script".

Click "Create New"

Select your script from the drop down and hit OK.


5. Review Script Log

Go to the dashboard of the unit that was in the group that you ran the script on.
On the right side: Click on "Configure" next to Script status.


In this window you should be able to see your script execution history which should look something like my output below.



Starting log (Run on device)
Script starts ...
config system interface

HQ_LAB (interface) #
edit internal
change table entry 'internal'
HQ_LAB (internal) #
end
cmd_clean_context 0, abort=0
HQ_LAB #
config log fortianalyzer setting

HQ_LAB (setting) #
set status enable
path=log.fortianalyzer, objname=setting, size=340, sz_attr=1
attr : status enable, 4, 0
HQ_LAB (setting) #
set source-ip 192.168.1.1
path=log.fortianalyzer, objname=setting, size=340, sz_attr=1
attr : source-ip 192.168.1.1, 4, 320
HQ_LAB (setting) #
end
cmd_clean_context 0, abort=0
HQ_LAB #

I hope this has helped some of you out there. Leave a comment if you have any questions.
Thank you!

No FortiManager, No Problem! [Windows]

Having a Fortimanager can get pricey. Not to mention risky when dealing with the latest builds and a large FGT network. In this post we will examine how we can run scripts/commands on your entire network without a manager by using open source software and the FortiOS CLI.

Download PLink


1. First create a working folder in your root drive. In the illustration below I have named my folder "putty".



2. Then inside the putty folder we will create the following folder structure to store our info. 

Devices / Logs / Scripts. Also save your plink.exe file in this root folder. 



3. Open your "devices" folder and create a new txt file. Add the interface IPs you will be connecting to via SSH in a single column.


4. Open the "scripts" folder and create a new txt with your commands.

This can be any command that you would be able to run in an SSH session on the Fortigate.

Refer to this post for CLI scripting help.

In this case I have used       
get system status | grep Serial-Number


5. Go back to your root folder "putty" and create a new txt file. Save it as "script_FGT.cmd". 

In this txt file we will be calling the script to run on your devices list and create a log in our logs folder. 

Replace username with your account username and password with the account password.

for /f %%i in (c:\putty\devices\devices.txt) do c:\putty\plink.exe username@%%i -pw password -m c:\putty\scripts\grepserial.txt >> c:\putty\logs\_LOG.txt



6. Finally, open a command prompt and run script_FGT.cmd.

How to setup a custom FortiClient install.

In this tutorial I will demonstrate how you should setup a custom Forticlient install for your users and include some example scripts to help you along.


1. Log into the Fortinet Support site and download the latest .zip package of Forticlient.

[Note that the install packages with _FG in the filename are for uploading directly to the Fortigate only.]


ftp://support.fortinet.com/FortiClient/v3.0/


See [LINK] for Readme.txt explanation of different install packages.


2. Unzip contents.


3. Install Forticlient.msi to a clean system/PC. Then proceed to configure the client as you would like it configured for your end-users.


[When installing; make sure to install only the components that you would like installed for your users as well. This will make the rest of the process a little simpler.]


See [LINK] for a sample FortiClient configuration.


4. Create a folder with a simple filename like "forticlient" in the root of C:\ and copy FCRepackager.exe and Forticlient MSI to it.

FCRepackager.exe can be found in FortiClientSetup_3.0.606\tools.

[Make sure you read FCRepackager_Readme.txt for all available switches and options.]




5. Run c:\forticlient\FCRepackager.exe -i AV,VPN,FW,WF -L p@ssw0rd -v at a DOS prompt.


This command string is executing the following:

Components installed:
AntiVirus,VPN,Firewall,WebFilter

Admin password = p@ssw0rd

Verbose Output:

This process creates the FortiClient.mst file which is required in the next steps. Make sure you place in the same folder as FortiClient.msi if it is not already located there.




6. Scripting the install.



A) To install Forticlient off of a network drive I like to use this little 2 part batch script.

[Make sure that move Forticlient.msi, FortiClient.mst and the scripts into the same folder on the server. In this case it is \\xSERVERx\FortiClient\MR7_Default_Install\.]

Step1.bat
cls
@echo off
TITLE Forticlient MR7 Patch3 Default Install

c:

net use v: \\xSERVERx\FortiClient\MR7_Default_Install


echo This is a silent install.......
echo You will be prompted when finished.
echo.

xcopy v:\*.* C:\Forticlient\*.* /F /Y


echo.
echo.
echo I mapped the install folder to V:\ and copied all of the contents to c:\Forticlient.
echo.
echo.
echo Another script will start and you will lose your connection to your network drives. Sorry.....

call c:\Forticlient\step2.bat

net use v: /delete

echo V:\ drive removed
echo Goodbye
exit

Step2.bat

@echo off
TITLE Forticlient MR7 Default Install [PART 2]

echo ......Installing..... Please Wait......

start /wait msiexec /i c:\Forticlient\FortiClient.msi TRANSFORMS=c:\Forticlient\FortiClient.mst /qn+

echo.
echo.
echo.
echo.
echo.

echo done

pause

B) To script a local install just recycle step2.bat from above. Just make sure that all of your files are in c:\forticlient.
