I think you may need to open up more ports on the router to get the game to work with both consoles. Try contacting Infinity Ward, Activision or Sony and see which ports need to be open. At least one of them should already be open as it's connecting with 1 of the PS3's, but maybe for the 2nd to connect another alternative port needs to be opened.
