VDOM with load-balancing FortiGate 100D

2 WAN connection combines to provide internet for a VDOM in fortigate. How to configure this is explained below.

Created VDOM for Wifi

Global > System > VDOM > Create New
Virtual Domain: Wifi
Inspection Mode: Proxy

OK

Assigned ports to VDOM wifi

Before moving ports to vdom, Make sure there are no reference to those ports from policies, routes, etc. Also make sure the ports have no IP assigned.

Global > Network > Interfaces >
Select and interface and Edit> change virtual domain of the interface.

In our case there is two WAN ports and and a LAN port for our Wifi topology.
(Port9 = LAN, Port 11 & Port 12 = WAN )

Now we need to create load balancing to combine the speed of both WAN connections. We can do this through FortiGate SD-WAN option.

Go to VDOM Wifi > Networ > SD-WAN > Enable SD-WAN
Click create New.
Seq1: Port 11 – Gateway IP is the IP of the 1st modem.
Seq2: Port 12 – Gateway IP is the IP of the 2nd Modem.

Select load balancing algorithm as “Volume”
Set the volume weight to 1 on both WAN connections.

Apply the changes.

Now create a SD-WAN status check.
It will check wan connection health against an external server.

Goto VDOM Wifi > Network > SD-WAN Status check> Create new
Name: Give a name
Protocol: Ping
Server: 8.8.8.8

Leave other stuff default. Then click ok. This will ocationally ping the google server through
the ports in SD-WAN to check the health of the connection.

Goto VDOM Wifi > Network > Static Routes
Destination: 0.0.0.0/0.0.0.0
Device: sd-wan
Admin distance:10
status: enabled

then press OK.

Assign a policy to allow traffic.
Goto VDOM Wifi > Policy and Objects> IPv4 policy > Create New
Name: Wireless devices
Incoming int: LAN port of the VDOM (port 9)
OutGoing int: SD-WAN
Select appropriate for Source, Destination, Schedule,Service, and Action.
Nat: on
Apply security profiles.
Log allowed traffic: log all sessions.

Now when we assign a new device to this policy the user will be able to access internet through the SD-WAN interface.

SOTI Mobicontrol: IP address, Firewall Issues!

Upcoming changes to SOTI Services may impact our operations.

SOTI is upgrading the infrastructure which hosts SOTI Services which are leveraged by SOTI MobiControl. The upgrade will result in SOTI MobiControl accessing SOTI Services via some additional IP addresses.

What Should You Do?

FAQs

    1. What is the reason for this change?
SOTI is upgrading its hosting infrastructure for improved performance and reliability.
    2. What is the impact of the change?
As a result of this change, SOTI MobiControl’s invocation of SOTI Services may occur on some new IP addresses. Enterprise networks which are configured to strictly whitelist only certain IP addresses will block these invocations unless the actions defined above are taken.
    3. Am I impacted?
Customers using SOTI MobiControl on a network where firewalls or other network appliances are in place, which restricts access to Internet services based on IP addresses, are impacted by this change.

Understanding scientific notation of large numbers

( Disclaimer: I am saving this here for my future use as a backup. Copy pasted from onlinemath4all.com . link to the original post is ==> https://www.onlinemath4all.com/scientific-notation-rules.html )


Scientific notation is a standard way of writing very large and very small numbers so that they’re easier to both compare and use in computations.

In this section, we will learn the rules which are required to write a number in scientific notation.

Scientific Notation Rules

Every number in the scientific notation must be in the form of

a x 10n

where ≤ a < 10 and n must be a positive or negative integer.

To convert a number into scientific notation, first we have to identify where the decimal point and non zero digit come.

There are two cases in it.

Case 1 : 

To move the decimal point to the left, we have to count number of digits as explained in the example given below.

According to the example given above, we have to move the decimal point 3 digits to the left and exponent of 10 should be 3 (positive integer)

When we do so, we get the scientific notation of the given number.

Hence, 2301.8 = 2.3018 x 10³

Case 2 : 

To move the decimal point to the right, we have to count number of digits as explained in the example given below.

According to the example given above, we have to move the decimal point 5 digits to the right and exponent of 10 should be -5 (negative integer)

When we do so, we get the scientific notation of the given number.

Hence, 0.000023 = 2.3 x 10

Important Note: 

If we don’t find decimal point at anywhere of the given number, we have to assume that there is decimal point at the end of the number.

For example, 

2300000 ————-> 2300000.

Here, the non zero digit comes first and decimal point comes next. So we have to apply case 1 to convert this number into scientific notation.

Scientific Notation Rules – Examples

Example 1 :

Write the given number in scientific notation.

0.00006

Solution :

Here decimal point comes first at non zero digit comes next.

We have to move the decimal point to the right.

No. of digits from the decimal point up to the first non zero digit is 5.

So, the decimal point has to be moved 5 digits to the right and exponent of 10 should be -5 (negative integer)

Hence, the scientific notation of 0.00006 is

6 x 10-5

Example 2 :

Write the given number in scientific notation.

5400000

Solution :

Here we don’t find decimal point in 5400000. So we have to assume that there is decimal point at the end .

Then, 5400000 ———> 5400000.

Here non zero digit comes first and decimal point comes next.

We have to move the decimal point to the left.

No. of digits between the 1st non zero digit and the decimal point is 6.

So, the decimal point has to be moved 6 digits to the left and exponent of 10 should be 6 (positive integer)

5400000  =  5.400000 x 106

5400000  =  5.4 x 106

Hence, the scientific notation of 5400000 is

5.4 x 106

(Here zeros after the decimal point are not taken. Because, they are not valid zeros)

Example 3 :

Write the given number in scientific notation.

71 x 102

Solution :

Here we don’t find decimal point in 71x 102. So we have to assume that there is decimal point at the end of 71

Then,

71 x 102 ———> 71. x 102

Here non zero digit comes first and decimal point comes next.

We have to move the decimal point to the left.

No. of digits between the 1st non zero digit and the decimal point is 1.

So, the decimal point has to be moved 1 digit to the left and exponent of 10 should be 1 (positive integer)

71. x 102 = 7.1 x 101 x 102

71

Hence, the scientific notation of 71 x 102 is

7.1 x 103

Example 4 :

Write the given number in scientific notation.

33 x 10-3

Solution :

Here we don’t find decimal point in 33 x 10-3 So we have to assume that there is decimal point at the end of 33

Then,

33 x 10-3 ———> 33. x 10-3 

Here non zero digit comes first and decimal point comes next.

We have to move the decimal point to the left.

No. of digits between the 1st non zero digit and the decimal point is 1.

So, the decimal point has to be moved 1 digit to the left and exponent of 10 should be 1 (positive integer)

33. x 10-3  = 3.3 x 101 x 10-3

33. x 10-3  = 3.3 x 10-2

Hence, the scientific notation of 33 x 10-3 is

3.3 x 10-2

Example 5 :

Write the given number in scientific notation.

0.63 x 10-3

Solution : 

Here decimal point comes first and non zero digit comes next.

We have to move the decimal point to the right.

No. of digits from the decimal point up to the first non zero digit is 1.

So, the decimal point has to be moved 1 digit to the right and exponent of 10 should be -1 (negative integer)

0.63 x 10-3  =  6.3 x 10-1 x 10-3

0.63 x 10-3  =  6.3 x 10-4

Hence, the scientific notation of 0.63 x 10-3 is

6.3 x 10-4

How to download a torrent

Things to know before we begin

  •  There’s no central server involved; data is downloaded from other users (seeders).
  •  you need a client application to download torrents.

Process is like this

Install client application ==> Search for the file ==> get the “.torrent” file ==> open it in client application ==> start download
There are tons of applications available on internet any of them would do. But I recommend using one of the following.

  1. deluge
  2. utorrent
  3. bittorrent
  4. Qbittorrent
  5. vuze
  6. BitComet
  7. Transmission

Now open a torrent search engine. Just like google but for searching torrents
(search google there is lot of them)

(Beware that most of the torrents nowadays are illegal. Use a VPN for protecting privacy when downloading torrents from internet.)

The speed at which you can download a torrent file is determined by the number of seeders available.

A seeder is a torrent user that has the entire file available for downloading. The number of leechers will affect your download speed as well. A leecher is a user that is downloading, but is not currently seeding. A leecher becomes a seeder when the full file has been downloaded. If there are significantly more leechers than seeders, the amount of bandwidth you receive will be lower, resulting in slower downloads.
Download torrents with a large number of seeders and of the best quality and size.
After downloading the .torrent file you need to open the file in any of the torrent client you have installed. The download will begin.
Alternatively you can use magnet links. In torrent sites you will see an option called magnet links. when clicked they will open your default torrent client and start the download. no need to download a .torrent file.
Some sites will give you a hash value for the torrent. you can use this value to download a torrent. in your client, go to file >> add a torrent from link. then paste the hash value.
the download will begin when you press enter.
