Just to let you know its solved. The kernel upgrade of the host from 2.6.20-16 to 2.6.22.14 on Ubuntu Gutsy seemed to do the job. It's defiently bridging correctly now with the guest reporting connections as coming from the proper hosts. Two other I learnt here that may be of use. If you are doing iptables and pppoe inside the guest, you must add this to your /etc/sysctl.conf net.bridge.bridge-nf-filter-pppoe-tagged=0 net.bridge.bridge-nf-call-iptables=0 Thats essentialy the bridge filter that filters that traffic is set to 1 (thats default) The other thing was the creation of the interface in /etc/network/interfaces auto br0 iface br0 inet static address 193.168.87.250 netmask 255.255.255.0 bridge_ports eth0 up /sbin/ifconfig eth0 inet 0.0.0.0 promisc I didnt know how to do the promisc mode automatically. The above line is it. So, thanks to those that responsed. Virtualbox performance has been awesome and I am def. a vmware convert.
