VMware ESXi 3.5- unable to access console of virtual machine after Wan IP change

[Jamsonlim]

Dear all,

We have running this VM Server for almost one year with any issue.

Last night we have relocated our VM Server to a new network with new WAN IP address allocated by ISP.

Prior to the server relocation, we have updated the Management IP of the VM Server but we did not update the IP address of the Virtual Machine.

After relocation, we were able to boot and access the VM Server, we can also power on the virtual machine using VMware Client.

When we want to access the console to update the new WAN IP address, it just give us a blank white screen. We have rebooted the machine many time but with no result to access all the virtual machine.

Is there any magic that we can access to the console of the virtual machine, any help is really appreciate as we have lot of important  data in the virtual machine.

We have phsyical access to the server.

Version of the VMware used.

VMWARE Infrastructure Client Version 2.5.0

VMware Esx Server 3i Verison 3.5.0

Virtual Machine - Centos 6 32bits

Thank you and we look forward to any advise!

Welcome to the Community,

do you have a firewall (port filters) between the Client and the host? Check whether the necessary ports (902/903) are open.

Dear Sir,

I have disabled all firewall on the client. A nmap port scan on the VMware server show,

Port 903 is missing.

Dear all,

No firewall in between server and client. I have disabled all firewall on client. How do I open up port 903 on the VM Server?

Thank for replying and your time is appreciated.

I could be wrong, but since you just relocated the host to a new network, I don't think this is something on the ESXi host, but rather something with a firewall setting on your ISP's network!?
