Unable to access the internet from my VirtualBox CentOS VM via wireless connection
4
I have a VirtualBox CentOS VM setup on my Windows 7 machine. I can ping my router, however I am unable to access the outside world.
In Windows I have three network connections setup:
- Wireless Network Connection (my WWW connection)
- VirtualBox Host-Only Network (my VM)
- Local Area Connection (unused)
I have my VM setup to use a bridged adapter to connect through the "Dell Wireless adapter".
Is there any reason why I should be unable to access the outside world from the VM?
I am trying to ping Google with:
ping 8.8.8.8
and getting connect: network is unreachable
This is a dump from ifconfig:

Can you visit your router page from the VM?

Feb 27 '12 at 14:29
There's no GUI installed, however if do a wget on the URL then i get a 401 unauthorized (as expected). I can ping the router successfully. Where do you think the issue is? With my router?
– crmpicco
Feb 27 '12 at 14:34
Not necessarily your router. Can you check whether the gateway is probably set on the VM guest, withipconfigorifconfigdepending on operating system. Because I guess it can reach the first hop but doesn't know where to sent packets to that have to travel more than a single hop (that thus are not in the network segment).

I've just updated the main question with a dump from ifconfig on my VM. Does that look like it is configured correctly? How can I tell if the gateway is correctly configured?
– crmpicco
Feb 27 '12 at 14:48
Oh right, that's different on Linux. You can see the routing information withroute -n, this would also show the gateway if it's configured properly.

Your routing table is incomplete.
Your computer only knows how to route to IPs that start with 192.168 and 169.254 but does not know how to route to any other IPs, we'll want any other IPs to be routed through your router.
If your router would be 192.168.1.1, you can for example execute:
route add default gw 192.168.1.1
This would cause the table to look like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0
0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0
For more information on how this works, execute man route.

OK, I have added my router's IP address (192.168.0.1) to the routing table and I can ping Google on the 8.8.8.8 IP. However, for some reason, I still cannot wget or access any domain (which is a big issue)? Does this mean it is a DNS problem?

Thanks, DNS was infact the problem. I added 8.8.8.8 and 8.8.4.4 as primary and secondary DNS servers respectively using the "setup" command in CentOS. This adds the records to your /etc/resolv.conf file. Thanks for your help!

Thanks, DNS was infact the problem. I added 8.8.8.8 and 8.8.4.4 as primary and secondary DNS servers respectively using the "setup" command in CentOS. This adds the records to your /etc/resolv.conf file. Thanks for your help!

OK, I have added my router's IP address (192.168.0.1) to the routing table and I can ping Google on the 8.8.8.8 IP. However, for some reason, I still cannot wget or access any domain (which is a big issue)? Does this mean it is a DNS problem?

Yes, it sound to me that you haven't followed any guide to set your internet up. Configure your DNS.

Can you visit your router page from the VM?

There's no GUI installed, however if do a wget on the URL then i get a 401 unauthorized (as expected). I can ping the router successfully. Where do you think the issue is? With my router?

Not necessarily your router. Can you check whether the gateway is probably set on the VM guest, with
ipconfigorifconfigdepending on operating system. Because I guess it can reach the first hop but doesn't know where to sent packets to that have to travel more than a single hop (that thus are not in the network segment).– Tom Wijsman

I've just updated the main question with a dump from ifconfig on my VM. Does that look like it is configured correctly? How can I tell if the gateway is correctly configured?

Oh right, that's different on Linux. You can see the routing information with
route -n, this would also show the gateway if it's configured properly.– Tom Wijsman
