Unknown handshake

[alexpp]

I just installed a clean TrueNas Scale on my device. Just enabled SSH Service, no docker, no VM.

But some weird handshake ocurrs periodically.

I realised this guy using TrueNas also has those weird handshakes

Anyone know what default modules in TrueNas required to connect those IP? and what's the usage for?

Is your NAS protected behind a firewall? Do you have port 22/tcp open to the Internet?
