We have a dedicated server with a hosting provider. We are running ESXi 6.0. The server has a single public IP which is currently being used for the management interface. The provider has also assigned us a /29 block so our VMs can have public IPs. We can only use 1 physical NIC, which I think is causing some of the problems.
They have told us that the default gateway of the IPs from this block should be set to the IP of the ESXi server. Whenever we try to configure this, VMs complain saying that the gateway is in a different subnet, which it is.
They have indicated that because of the way their network is configured, we need to route any IPs from the block they assigned us through the IP of the ESXi server. From what I know, ESXi doesn't support routing, making this impossible.
We've asked if they can assign this block (or even a single IP) to the server so that they are the same as the ESXi IP so we can use them on VMs, but they have told us that their network setup does not allow for this.
Ideally, we want to be able to assign these public IPs to our VMs so that they are directly accessible from the internet. Is there a way to do this? Are we missing something?
If the above isn't possible, is there a way for us to do port-forwarding/anything else, so that we can reach our VMs from the internet?
We have not changed any networking configuration in ESXi, so we still have just a single vSwtich with both the management network and VM network attached to it. This vSwitch is attached to a single physical NIC on the server, which all IPs are assigned to.
Happy to provide any additional information if needed.
