Seals need help again please

i got the seals in my diff. housing now, now im putting new wheel bearings and seals in . My question is after i put the bearing and Snap Ring in the outer housing which way do the seals go in . Both seals have a flare lip on them do they both face with the flare lip turned away from the bearing or what. Im guessing the flare goes against axle and the other one goes against the hub but just not sure i know you guys know the answer. thanks for all the great help again. also how tight should i tighten the axle nut is there a torque for the nut or what.
