I currently have a net-bsd firewall running with a static ip and a 
dynamicip.  The static is bimaped to an internal server, and the 
dynamic is shared by the other computers on the network.  Is it 
possible to remove the static IP and have any traffic that doesn't 
have an active connection default to the internal server? I tried 
bimaping th 0.0.0.0/32 address, but this didn't work.  Any ideas?

Thanks
Ben
