@KaSper(S)ky:
The first picture was the ip address 192.168.4.1, and later I changed to the 192.168.4.2.
Later changed what to 192.168.4.2? Clearly you changed the IP address you told the browser but did you also change the IP address of the pfSense LAN interface?
And why did you change what you changed?
On the information you have supplied I'm left believing you have your pfSense LAN interface with IP address 192.168.4.1 and you are attempting to access the pfSense web interface by accessing IP address 192.168.4.2 and complaining you can't access it. If you can't see what is wrong with that combination then you are out of your depth and probably need to get help from someone who can sit beside you and watch what you are doing and challenge you immediately you do something "unusual".
Maybe you just "forgot" to say you had also changed the pfSense LAN interface IP address to 192.168.4.2. If you repeatedly give me incorrect information or "forget" to tell me you just made a change or a few changes to my suggestions then I'm likely to feel my time would be better spent working with someone who provides accurate configuration data and closely follows my suggestions and tells when they do something different and why they did something different.

I dont set up default getway because I dont know which ip address should be standing there.
I hope you know now what the default gateway IP address should be.

Version 1.2.3 works fine while 2.0.1 is not. That's why I asked for help with the setup version 1.2.3.
I would be very happy to step aside if another reader wants to help you with pfSense 1.2.3. I'm not prepared to give you any assistance with pfSense 1.2.3.
