PIX, inside interface drops return ping packets HELP.

Hi all, I have a problem with pinging outside
Current lab

R1 ----PIX----R2

R1 is on outside interface
R2 is on inside interface

IP R1 e0/0 = 82.111.43.1
IP R2 e0/0 = 10.1.5.2
PIX IP

Inside = 10.1.5.3
Outside = 82.111.43.3

Current access-lists on PIX(yes I just want to see what’s happing here, so gave the hell to come loose)

access-list 100 permit ip 10.1.5.0 255.255.255.0 any
access-list 100 permit tcp 10.1.5.0 255.255.255.0 any
access-list 100 permit udp 10.1.5.0 255.255.255.0 any
access-list 100 permit icmp 10.1.5.0 255.255.255.0 any
access-list 100 permit icmp 10.1.5.0 255.255.255.0 any echo
access-list 100 permit ip any 10.1.5.0 255.255.255.0
access-list 101 permit ip 10.1.5.0 255.255.255.0 any

access-g 100 in int inside

IP route outside 0 0 82.111.43.3
IP route inside 0 0 10.1.5.3

Nat translation (PAT)

Nat (inside) 1 0 0
Global (outside) 1 82.111.43.4 netmask 255.255.255.255

Any help everyone, at least point me in to the right direction

If you want the config let me know by the way I can telnet to port 80 though
R2#telnet 82.111.43.1 80
Trying 82.111.43.1, 80 ... Open
