Default TrevE modified android tether app?

I aware that our stock hot spot works but I want to know if someone has successfully used the WiFi tether for root users app? And what settings cus I've tryed about every settings possible with no luck, reason I'm asking is cus when I try play Ghost on ps3 my NAT is set to strick, when I had my evo3d stock hot spot did same but android tether would open my NAT....I have hard time joining a party
