firestarter only controlling port forwarding connections

[Noah]

Hi there,

I find with firestarter that when I have port forwarding turned on for a 
particular port the IPs in the "Allow connections from host" rules.  I 
want the order of events to be:

1) Allow connections from host
2) then follow port forward rules.

How can I configure firestarter to do that?

Cheers,

Noah
