DNS IP address for VMWare box

SBS2011 TCPIPSBS2011 DHCPI have setup a VMWare box with ESXi V5.5.
I assigned to VMWare box and as Default Gateway and Primary DNS Server.

In the VMWare server, I have one VM which runs SBS2011 with  IP address:
Please see the screenshots above.

I have internet router which has IP address of

I like to know if I assigned the right IP address (  for Default Gateway and Primary DNS server on VMWare box. Or should I be IP address of SBS2011 (

As long as your SBS server provides DNS for your organization, I would point your host to the SBS. Just remember to point in a host a-record in DNS, so that it's reachable by name, whatever name you gave your host.

The DNS server setting point to an IP address, which host the DNS server. AS SBS usually installs a DNS server, it should be the SBS.

Now it depends what you want to realize. If the VMWare host has the IP of the router as a DNS server, the router has to answer to DNS requests. That means, the router has first to have the capability to act as DNS and second he has to be aware about the targets, it is asked for. As your router possibl doesn't know something about your windows network and tries to send any request to the internet, the configuration may be as follwos.

All your internal clients point to SBS as DNS to be capable to resolve internal names. The SBS DNS router has configured "Forwarders", which are DNS servers which are capable to resolve external names (this can be the router). This way, all names can be resolved.

So if your DNS is configured with forwarders to resolve external names, the SBS is the right DNS server for you.

As DNS servers works in a chain, one DNS forwars unknown reuqests to the next available DNS, you have to make sure, the chain can work.

So you are suggesting that I assign the ip address of SBS2011 ( instead of using internet router IP address ( as both Default Gateway and Primary DNS Server?

I am just curious if it makes any difference whether I use or
If it does, why?

"Just remember to point in a host a-record in DNS, so that it's reachable by name, whatever name you gave your host. " --> can you rephrase? I don't quite understand.

You should definitely *not* set the default gateway to the SBS server. While it is rare that you'd want the VMWare host to go outside the local LAN, if you ever were in a situation where you needed it to, the default gateway would be wrong and connections would fail. If your gateway is then that is what you should set it to in VMWare. SBS does not provide any gateway or proxy functionality.

As for DNS, *that* should point to SBS. Most things will work even if it isn't pointed to SBS, but if you ever decide to do any advanced scenarios such as AD/LDAP integration, this will make troubleshooting much easier. Always better to set it up "right" the first time instead of making changes later.

So, change your DNS setting. Do not change your gateway. Pretty straightfoward and hopefully clears up any confusion.

My original comment was about setting your DNS as sbs IP address, not your default gateway.
In regards to the a-record, open up your DNS management console, find the forward lookup zone for your domain and then right-click and add a static record of your vsphere host with its IP address, whatever name you configured your host with. This way you will be able to connect to your host by name.
As previous poster noted, set it up correct the first time, which bring me to the next point. It's best to have your management network on a separate subnet than the rest of your infrastructure. Same goes for vmotion network and iscsi. This will complicate things initially, but will provide you with much greater flexibility as your enterprise grows.
Jepp, just to clarify and answer our request.
DNS setup to SBS, the gateway is into question

...wrong button....
...the default gateway handles all traffic, what do not have a local target. So, if you want to connect your VPM host to connect to the internet, you can setup the default gateway to the router. If this is a good idea depends from the question, how well the router can protect your vm host. For your internal network, you do not need to setup the default gateway.

DNS to SMB (possible with forwarders if needed).
Gateway empty (no internet access) or the router (with internet access)

I changed Primary DNS Server to (SBS2011) and changed the host name on VMWare Box to "VMWare1". But I don't see the name "VMWare1" in  SBS2011 DNS yet.
I left Default Gateway to  At this point I can't think of the reason to access this host over the internet, but just in case.

As mentioned, you need to put in host a-record in your DNS, that's the only way it would be accessible within your network.

okay I'll try that later and post the results

Since I can access VMWare Host ( by IP address, I don't see much the benefit of adding the entry to DNS.
