Ssh – Bind SSH port forwarding to IP by user

ssh

Is it possible to bind a specific user to a certain IP when using port forwarding (preferably dynamic) in SSH? I don't mind if it has to be done by the user, but by the server configuration would be preferred.

Basically what's happening is I have multiple addresses on the machine, one is the default eth0 (let's say 192.168.1.100) and another is eth0:1 (192.168.1.101). When I open a dynamic tunnel (ssh -D 1080 192.168.1.100) from a remote machine, I'd like all my traffic to appear as if it's coming from .101 instead of the default .100.

Is there any way of doing this short of going with a solution that binds an entire user to an IP? Or, potentially, configuring a local SOCKS application and just local forwarding to that port instead?
