I have a Win7 host machine with Vmware Workstation. In the workstation I have 3 Ubuntu installed. All 3 Ubuntu guests have a Nat network - to access the internet without asking the router for a local address - and a Host-only network - to connect all Ubuntu quests and the host in a private network for internal communication, without touching the router.

When I try to make any of the Ubuntu quests to get data from the internet - assuming that they would figure out that the Nat-ed interface can access the requested data - they fail and report that there is no route to my query.

If I disconnect the 2nd interface on the Ubuntu guests with the Host-only network and restart networking, they start to know the route to the internet.

Odd, during the installation of the guests they asked which of the 2 given interfaces - with Nat and Host-only config - should be used to get updates during installation and they oddly managed to get the updates. Not so after the installation has finished and rebooted.

I have checked the Virtual Network Editor that the Nat interface should use my real network card to access the net, so there should be no problem.

I wish not to use the router's dhcp service to give the Ubuntu quests an address, and also I don't want the guests to be accessable from the local network directly, but only by the host - that's the Host-only network is for.

Any suggestions?

Edit: 192.168.189.0 is the Nat interface and 192.168.7.0 is the Host-only.
