You can’t access the pix from the internet using telnet. You will have to use SSH. Here is the basic config for a PIX

! enable the outside & inside interfaces
interface ethernet0 auto
interface ethernet1 auto

! give the interface a name and security level
nameif ethernet0 outside security0
nameif ethernet1 inside security100

! IP address
ip address outside 68.1.1.2 255.255.255.252
ip address inside 172.16.1.1 255.255.255.0

! Define your NAT for internet access
global (outside) 1 interface
nat (inside) 1 0.0.0.0 0.0.0.0 0 0

! Define your gateway
route outside 0.0.0.0 0.0.0.0 68.1.1.1 1

! Allow telnet from the inside
telnet 0.0.0.0 0.0.0.0 inside

configuring SSH is another lesson
