VMware + Ubuntu Linux NAT will not allow internet access

BlackHawk · 12-16-2012, 10:45 PM

Hello everyone, just last night I came across a weird problem...

Okay well here is my setup...

I have Windows 7 running as my Host OS. I have Ubuntu Linux running as my Guest OS. Now I have pretty much always used NAT as my network setting for VMWare player, yet last night for no reason my internet just stopped working. I did not alter any host/router files or do any kind of network configurations.

So i figured it was just a problem a simple reboot would fix but when I did reboot my computer and ran vmware player again and started linux with NAT my internet was not working.

Now when I would do a ping for google i would get this kind of reply.

ping google.com
ping: unknown host google.com

Now i have no idea what could have caused this, I swear to you all I did not touch anything!

Okay so let me give you some info...

The thing i notice in that is that my vmware adapters VMNet8 and VMNet1 have dhcp disabled or not enabled however you want to word it.

I am not sure if enabling them will solve this, and if it will how do i enable it with windows?

Here is output from linux:

Code:

eth0      Link encap:Ethernet  HWaddr 00:0c:29:7b:4c:67

from /etc/hosts

127.0.0.1 localhost
127.0.1.1 bt.foo.org bt

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

and from /etc/resolv.conf

nameserver 192.168.142.2
domain localdomain
search localdomain

Now when I am in NAT with vmware player i can ping 8.8.8.8 and I can ping my router 192.168.1.1 but nothing else works.

One other thing that is a bit weird, when I switch from NAT to BRIDGED with vmware player I can connect to the internet just fine, everything works great.

I would really like to figure out what happened here so if this problem arises in the future I will know how to resolve it.

A few things I have tried...

I tried in Windows 7 in my Vmnet8 and Vmnet1 adapter settings, I tried editing IPv4 and instead of using the ip address 192.168.254.1 i selected to get ip address automatically and that did not work.

I also tried disabling ipv6 in my VMNet8 and VMNet1 adapter settings and that did not work.

In linux i tried:
ifconfig eth0 down
ifconfig eth0 up
network restart

and that did not work either...

So i am really lost about what to do now...

Why is it working with BRIDGED but not with NAT??

If anyone has any input I would really appreciate it because I am lost about what to do on this issue...

Thank you all for your time and your assistance.

Oh and on a side note on WIN 7 i went to administrative tools -> services -> and check NAT for Vmware and everything vmware related was at "started" and also set to "automatic" so i don't think that is the issue...

When pinging google.com you are testing your DNS as well as the underlying network connectivity, which is bad practice.
Ping IP addresses to test the network, ping names to test DNS

Your DNS server is privately addressed, so it is probably your own - is it working?
