Before, after enable VPN, Mikrotik

I am doing Mikrotik router reset (without restore from backup) and this is my basic preparation:
1) set up router name
2) set country
3) set password for wireless
4) change subnet octet
5) apply configuration:

I am setting this up via wireless connection.

This means when I hit [Apply Configuration] I will be automatically disconnected from wireless network!

I must connect to the new wifi network now.

I am barely know how to work wit Firewall Rules and NAT. This time my plan is to take some screenshots with default firewall rules and NAT configuration. Maybe I will learn something :)

I will enable VPN and the look what is changed:

The result is this..

By default on RouterOS have 7 firewall rules:

After enabling VPN there are three more rules:

Now I know what created these rules. The checkbox which I pressed once created these rules. This is important. I know where this content should be always located. Before any drop action I guess.

NAT section before VPN:

After VPN was activated there is new masquerade. What is that means?

Ok. I will leave it there forever.
