Hi All,

VirtualBox 4.0.0 on Windows 7 Ultimate 64bit.

I've installed 64bit Centos 5.5, Fedora 14 and Ubuntu 10.10 Virtual machines and all can connect to the internet fine using NAT.

However when I change the Network to Bridged and give the Virtual Machine a static IP address (with correct subnet and Default Gateway/DNS set to my routers IP) I find that
I get timeouts when connecting to web sites.

This is occurring on the Fedora/CentOS machines only - the Ubuntu machine seems to work fine.

I have a felling this may be something to do with ipv6 so I disabled ipv6 config for the interface, disabled the ipv6tables service, added blacklist ipv6 to blacklist.conf and set NETWORKING_IPV6=no to /etc/sysconfig/network

but it still fails to open web pages (timeout message). I can ping external websites fine and dns seems to be working ok for external addresses.

I can get to internal network web sites OK too (e.g. router admin).

Does anyone have any ideas on what this problem can be?

p.s. same issue with Fedora/CentOS on machine with VirtualBox 3.2.12 host.

thanks,
Tom.

Post the results of ifconfig -a for the two that are not working.
Make sure that you have selected the Bridged mode before you do this.

Apologies.

I mistakenly said in my original post that Ubuntu was not having this problem (not sure why I thought it hadn't) which shifted focus away from the underlying problem.

Which was the avast! Firewall NDIS Filter Driver.

The solution was to either disable this from the Network Adapter or to go into "Expert Settings" in the firewall config and choose "Internet Connection Sharing Mode"
