Aiuto su pix 501 nat

[Chick75]

ciao raga, ho un problema di questo tipo:

pc(lan interna) ----> Pix501 ----- Cisco 857 Router

i pc della lan non riescono a navigare in internet. Suppongo sia un problema di nat... siccome è il primo pix che configuro mi dareste una mano? Grazie mille !!! allego sh run
