Help, getting attacked

Hello, today I realized that someone is trying to brute force my RDP Server since a few days.

So I switched of the NAT rule for RDP.

Still the attack keeps going on, the UTM does its work and drops the packets. Since I am getting attacked from multiple IP Adresses, is there anyway to stop this?

Or do I just have to wait until the attacker is stopping it?

Thank you for your thoughts!

    I absolutely agree with you, we are all living such a high living standard.

    I hope you are still that sporty! Never went fencing but heard that it is a lot of fun.

    Have a great saturday!
