WRT320N. Port forwarding help. Xbox and ps3 playing at same time. NAT issues

Question

Hi
I'm trying to have both my xbox and ps3 play with open NAT's for online gaming. I have had success utilizing info from 'portforward.com'. But the solutions will unlock OPEN NAT for either the ps3 or the xbox .. one at a time. Is there a way to get both to be open?
It seems like one main conflict is the success depends on both utilizing port 3074. But I can't have both use it? ( obviously).
I tried port forwarding the xbox per specs off of this forum and that works great.. And DMZ ing the PS3. But like i said before. Most solutions
leave one console with OPEN and one with Moderate.
Is there a solution that allows both NAT OPEN's on both consoles?
