Port forwading in split tunnel mode

Is it possible to have port forwarding work with a RED in split tunnel mode?

So the scenario is that all computers on the red network will be getting dhcp and dns from the central asg. What I'd like to do is have external traffic that comes in to the asg's public ip at say port 7000 directed to a particular ip address (computer) on a specific RED network. And when traffic would come in on say port 8000 have that go to a specific ip (computer) on a different ReD network.

Thanks.
