Cannot connect to other Hosts from ESXi with ssh/scp

Hi there,

I have two ESXi hosts (free Version 6.5) up and running for quite some time now. Everything is running smooth.

If SSHd is enabled on the ESXi hosts, I also can connet to then with ssh, there is no issue.

But if I'm already on the ESXi host in a shell, I cannot connect to any other host with ssh or scp.

ssh: connect to host XX.XX.XX.XX port 22: Connection timed out

This behaviour is the same for both of my ESXi hosts. SSHD on the remote hosts (where I want to connect to) is working fine, and I can connect to them from any other machine beside my two ESXi hosts.

Any clue from where this behaviour comes and how to fix it?

Regards,

Claude
