Bridged Networking -- Guest doesn't See Host; Sees Everything Else

[jwatte]

I am running Ubunty 10.04 as a guest on Windows 7 Workstation x64 using VMWare Workstation 7.1.

My networking is configured as Bridged (VMNet0), and I have disabled the VMNet1 and VMNet8 devices just to make sure they don't accidentally interfere.

The host can ping the guest by IP, and get to ports exposed by the guest. This is good. The host can also get to other hosts, on local and internet addresses.

The guest can get to other hosts, on local and internet addresses. However, it cannot get to the host (by IP or by name, although only by IP matters).

The host is assigned address 192.168.1.103 by the DHCP server in the local network; the guest 192.168.1.109.

Here are host networking details:

The host has a few installed network adapters:

- wireless (generally in use, and in use in this case)

- wired (sometimes in use, not in use in this case)

- VPN (not in use at this time)

- WLAN (not in use at this time)

Plus the Windows Teredo tunneling ipv6 stuff and whatnot. Seems you can't throw a rock around here without hitting yet another virtual network adapter these days 😕

I have installed the VMWare Additions on the guest.

I need for the guest to be able to see the host (and, specifically, services on ports exposed on the host), in addition to the host seeing the guest. How do I make that happen?

[jwatte]

The problem seems to be related to the "automatic bridging" option.

When I specified my wireless hardware interface in the bridging options, I can now connect using HTTP from the guest to a server running on the host. Ping still doesn't work. Also, trying to connect to addresses of other interfaces on the host from the guest doesn't work.

This is enough for me to limp along for now, even though it's still somewhat broken.

[jwatte]

And this has now broken again.

I'm running 7.1, Windows 7 x64 host, Ubuntu 10.04 LTS x64 guest.

The configuration is Dell 1510 wireless network adapter as specified bridged adapter.

The guest gest an IP (192.168.1.107) and can talk to the world.

The host has an IP (192.168.1.105) and can talk to the world.

However, the two cannot talk to each other. Specifically, services running on the guest aren't seen by the host, and the host cannot ping the guest.

I've also tried using a private network (VMNet1), and they still can't talk to each other.

I'm attaching my vmware.log from the guest install directory on the host, on the off chance that it might help.

It seems that you have changed the defaults. You use a custom network and it ius called VMnet0. By default VMnet0 is the bridge, so to use a bridged connection you just have to choose "bridge" as the virtual NIC type.

Can you post screenshots of the single tabs in the virtual network editor, please?

hi all. I have exactly the same problem.

But I have some clarification:The problem is the network connection of the real host on which you installed VMware Workstation and virtual hosts on it.

1. A network connection virtual host with other hosts on a real network, the bridge is functioning normally.

2. But between the carrier and VMware Workstation virtual host as follows:

Any ideas why this is happening?

P.S.

Virtual Network Editor settings:

Or

Virtual host settings:

Or

And sorry for my english.

Yes, I have changed the default bridging, because "automatic bridging" didn't work at all. I think it picked up an unconnected wired network adapter, or perhaps my WAN card.

Here is a screen shot of the virtual network editor. As you can see, VMnet0 is still bridged, tied specifically to the Dell Wireless 1510 Wireless network adapter.

I also include a screen shot of the configuration for the VM, to show that it's connected to this virtual network.

[AWo · Accepted solution]

You can use "bridged", no need to use custom. It is a good practise to change automatic bridging for VMnet0 to a fixed adapter like you have it.

Change it to bridged, now and report the status.

Yep, works now. Thanks!
