Does the vSwitch that is connected to the different subnet have a service console or vmkernel with an assigned IP address? If so is it possible to reach that IP address from the different subnet? If not it may be a routing issue with the network.

Could you post more information about the network and vSwitch configuration? Are you using VLAN's? What are your firewall settings? As long as you can reach the IP address of the service console from the different subnet, you "should" be ok.

I have one subnet and No v-lans. I think this is a security setting on the ESX server it's self. How bes may i gather the other information you are asking? Where and how can I view teh ESX network Config / Settings?

Thank you.

On your ESX host, the management network, can it ping its gateway? If yes, then it's a routing issue. If it can't, then it may also be a routing issue. Can the ESX host ping other hosts on the same network segment? Then, it's not a Layer 2 issue, and is definitely a routing issue.

Yes, from the ESX server I can ping the PC that I am trying to Manage the ESX server from. i can not access the web page on teh ESX server at all from teh workstation. How can I look at the network setting on the ESX server and the security?

Ok, if you can ping your client from your esx host, then routing is not an issue. Have you verified that you don't have windows firewall enabled and running on your client?

Not at all. I manage my hosts from a different subnet and have no issues. There is nothing by default that is preventing this.

Since you can ping the client from ESX, but not the other way around, I'd say there's some kind of network config mismatch. Does your client machine have the same subnet mask as esx? I've seen one-sided issues occur when masks don't match.

I am lost then it's a QA environment I can grant you access via RDP if you provide me with a log in ID and PW that you would like to use.

I am just plane lost a this point and am not so sure I am asking the right question in the first place.

Kind Regards,

Taylor
