I have also set up an internal network on eth1 with a bridge so the instances, which all have fixed private IP addresses (e.g. 192.168.4.x) should be able to ping the public Internet through this bridge. However, this isn't working, and I'm hoping you can help explain what I'm doing wrong.

My instances are able to access the public Internet if I change my configuration to use a floating range, but I prefer to find a solution that allows me to assign an internal IP to my instances and use the specified bridge to contact the outside world.
