I have got a VMware Server 2 on a CentOS 5.6 host. I can access my virtual machines from the host machine, but I can not access it from other machines.

I have configured NAT port forwarding. But somehow I have no access to the VM using ssh. I have checked all firewall settings and they seem right.

What can cause this problem?

Hi Bilal - someone would need much more detail to answer your question. From what I understand, you have an ESX v2 box w/a Cent 5.6 VM on it? If that is the case, which firewall are you talking about - on the hypervisor (ESX box) or the VM? Where's the other system you're ssh-ing to/from? It sounds like your vSwitch needs some love, but I need more detail. – mjb Jul 8 '11 at 17:00
no i have vmware server 2 on centos 5.6 as i mentioned. I am talking about firewall of host machine. i have ssh access from host to vm, i have ssh access over internet (out of network) to host, but i have no direct access to vm throug ssh. – bilal Jul 8 '11 at 18:53
That makes more sense - thanks for the clarification – mjb Jul 8 '11 at 21:29

There are two separate networks you are dealing with here. I'll give you an example:

IP your ISP gives you = 22.24.42.44
IP of your router = 192.168.2.1
Host System IP = 192.168.2.2
IP of your VM = 10.5.5.4

This configuration is how my virtual environment's networking looks. So you actually have two networks you would have to port forward across to get Public access to your VM. Think of it like your hypervisor (host system) IS a router for your VM.

I followed this how-to to setup my config, but you may have a more complex configuration.. it depends on what application you want to run - RDC, apache, ssh. There is more good information here. You'll have to give more detail than I would want to ask for on a public site for me to help with specifics. The principles are always the same -- make a localhost:<> connection to your physical system forward through VMware Server 2 to the VM port you want to access (22 for SSH).

my configuration is exactly same like your how-to link. i am forwarding an Ip on my host for example: 2222 to 22 of my vm in my nat config. 2222 : xxx.xxx.xxx.xxx:22 – bilal Jul 8 '11 at 21:41
by the way i am getting server unexpectedly closed network connection, if it gives more information – bilal Jul 8 '11 at 22:49
can you ssh on the same subnet? From a host on the same IP range (192.168.2.x in the example above)? – mjb Jul 11 '11 at 19:21
