I have installed Vmware ESX3.5iu3 on a Dell PE 2900.
Configured it with 3 VM's
SBS 2003R2
Windows 2008 Std.
RCLI
After configuring the SBS and Windows servers I have shutdown the server last night. This morning after booting I am not able to ping any machine from the SBS or W2k8 VM.
after rebooting the VM's I am able to ping the network again. Looks like that problem is solved. But still I am wondering:
On the Host ->Configuration -> Security Profile
There should be firewall Configuration there, but Instead I see a short blink of firewall immediately replaced with Services. below that is says :
Vmware Virtual Center Agent
NTP Daemon
The Agent is stopped
The NTP is running.
How do I access the Firewall settings again??
No more firewall on ESXi. (The firewall was handled by the Red Hat Linux Enterprise "Service Console" with iptables)
Thanks for clearing that out.
Does this also mean the network is connected without anything possibly interfering with the physical network. So if I have networking problems, they are not related to some sort of firewall/ configuration of any, besides ofcourse configuration of the networking it self?
Seems to be, be sure to check VM settings and on what portgroup it's attached (ensure connected checkbox are checked) and re-apply configuration.
After that if it still not works should be a Guest Operating system misconfiguration or security rules standing somewhere.
ESXi does have a firewall for the vmkernel ports similar to what ESX has for the service console. It's just that with ESXi there's nothing to configure in the GUI to change the firewall as you wouldn't be adding agents, etc as you would with ESX.
That said, in both ESX and ESXi the firewall does not affect the virtual machine ports so all traffic / ports will be open to your VMs.
