Welcome to the community

make sure if the esxi firewall is configured to allow serial port communication of the virtual machine.

Adding a Firewall Rule Set for Serial Port Network Connections

If you add or configure a serial port that is backed by a remote network connection, ESXi firewall settings can prevent transmissions.

Before you connect network-backed virtual serial ports, you must add one of the following firewall rule sets to prevent the firewall from blocking communication:

■	VM serial port connected to vSPC. Use to connect the serial port output through a network with the Use virtual serial port concentrator option enabled to allow only outgoing communication from the host.
■	VM serial port connected over network. Use to connect the serial port output through a network without the virtual serial port concentrator

hi,

I have a very simillar problem as follows :

VM IP : 172.17.1.5

ESX HOST IP : 172.17.0.78

1. VM set in my esxi 5.1

2. added serial port

3. Use Network > Act as server, port uri is telnet://172.17.1.5:1234

4. ESXi firewall rule is enabled for Serial over Network

When I try to connect with telnet to vm ip or to esx host ip it does not work, and i can't find any examples anywhere...

I shoud try to telnet into the esxi host into vmk0 ( Management network ) requesting the specific port and that the esxi should forward the request to the apropriate vm. ? or I should telnet directly to the vm ip:port

What should be entered in the Server URI ? the ip adress of the vm or the ip adress of the esx host ( vmk0 ip ) ?
