This is supposed to be very simple.
I'm using ESXi 6.7.0 Update 3 (Build 16075168). This is the latest patches applied to date.
Can't get the Serial port over network working for any of my guests. I have Cisco XRv9k VGA and non-VGA, Nexus 9300v, Windows, Cisco CSR1000v.
Added serial ports backing telnet://:XXXXX in multitude of them.
Updated Firewall rule to allow serial connections "VM serial port connected over network" remoteSerialPort enabled true.
Checked with esxcli it allows ports 1024 upwards.
Powering on the guests, Serial ports says Connected = No on the Web Gui.
Checked with NMAP. VMware host is not listening any of the tcp XXXXX port I configured anyway. So no connection possible.
Tried 'telnet hostip XXXXX' obviously anyway. "Connection Refused".
Any ideas?
