is it a risk for my main computer ?

Because the vps where I have installed the t-pot doesn't have any graphic cards (GPU), I must connect to the honeypot through RDP. I connect to the t-pot honeypot directly from my main computer. Are there any risks for my main computer, because of this? Could the honeypot attacker, attack my main computer through the rdp client, or find my public ip, from the main computer?

If the honeypot is compromised because of your lack of knowledge, yes, your computer could be at risk.  Since you ask this question, I think you need to further your knowledge about this topic before implementing it.

Thank you for your answer Dominique1. Another person, on another forum, has answered:

"As T-Pot use all available ports as a honeypot is design for, this do not mean your client is exposed."

Would you agree with that answer?

Indeed, I am a very beginner, if you do not accept the above idea, can you give me please, some more details, some options/scenarios, how my main computer. which I use to connect through RDP to the vps where is the honeypot installed, could be attacked? Thank you.
