I assume you have one subnet ( and your server is 
configured as a bridge. If you aren't running as a bridge then I 
believe you would have an invalid network configuration.

Unfortunately, as far as I know there is no way to allocate addresses 
as you wish. I don't think there is anything in the inbound packet to 
identify the interface, and the interface isn't available as a 
parameter to use in a match statement.

Incidentally, for those more familiar with the implementation (David 
?). How does the server deal with a bridge setup, does it have the 
ability to look at a bridge the interface is a member of to find the 
IP address and so select the right subnet, or does it require the 
interface to have an IP ?
