Ubuntu server + KVM. Guest os can reach wan but host machine cannot

[fistikuffs]

Hi there. I have a strange problem here. I've set up ubuntu server 10.04 x64 with kvm and bridged networking and installed win server 2008 as a guest os. The guest os has full access to the network including lan/wan but the host os can only reach my lan and not the wan. This is true even when the guest machine is powered off?

I have to admit that my knowledge of networking, particularly with respect to linux is very flakey but surely if the guest has internet access this should also apply to the host? My only suggestion is an issue with mac addresses but i don't know where to start. Has anybody ran into this problem before?

Thanks
