Unfortunately, tcpwrapper doesn't allow for this. tcpwrapper either blocks/allows a protocol based on the "source" not the "destination". The issue is that tcpwrapper is called too late in the network layer to determine what interface the packet came in on. You should look into a firewall (e.g. Sun's Sunscreen) to do something like this. Sorry this isn't the answer you wanted, but its the only one for this situation.

Have you looked at xinetd, it's a replacement
that allows for more control than tcpwrapper does
like binding an application to an ip address.
It also allows to folter on source address.
