Port forwarding to listen on designated interface

Hi list.

I'm using the -L option to set up an ssh tunnel to a remote host.

I would like to be able to specify the local network device that ssh
listens on.  With the -g option, ssh will listen on the designated
port on *all* local interfaces.  Without the -g option, ssh will
listen only on the loopback device.  I would like to be able to get it
to listen on a device that I nominate (e.g. a dummy network device, or
a second loopback device).

I know I can achive what I want by using the -g option and using
ipchains to filter out connections on the devices that I don't want to
listen on, but I was hoping there was a neater way.

Thanks in advance,
Josh
