RDP attacks to bitcoin nodes

[amaclin]

I see a lot of attempts to gain access rights to the server with my bitcoin node.
Attackers try to connect to it with RDP (port 3389)
How can I block all incoming connections to 3389 except of my own IP-address?
Right now I add IP-addresses to a "black-list"

3389 port is for remote desktop protocol on windows ,  everyone can connect remote windows server via RDP  .
SO ... Hackers always like testing 3389 port using weak password  no matter what services you run

You can try this: Limiting access of RDP to a certain IP only. It has two suggestions (the firewall one might be harder depending on experience). Another thing, this section isn't for discussions such as this one.
