How could I configure my Smartbro broadband to my Ubuntu 10.04 LTS? I run it through a virtual box via USB. My OS is Windows XP sp3 Ultimate Edition. Thanks.
VirtualBox normally shares your network connection automatically. No additional configuration should be required.
Maybe right-click your virtual machine, go into the settings menu, look under networking and verify that "Network Address Translation" or "NAT" is being used? That should be the easiest method.
