ICMP echo-request: untranslating outside - No Ping response

Tags: untranslating, icmp, echo, request, outside
Hi please Help

I got a Huge Grane waiting for remote thousands miles away !!

I'm trying to access from the outside interface using ping from a router 172.24.16.5, where there is a
ip route 172.24.16.8 255.255.255.255 172.24.16.7

The device i'm trying to ping is on the inside side of the pix and has ip of 10.10.10.175 and responds to ping from the PIX

the router 172.24.16.5 on the outside side of the pix also reponds to pings from the pix

Enabling debug iCMP trace and pinging 172.24.16.8 from the router 172.24.16.5 i do get the following messages
----------------------------------------------------------------------------------------------------

macaefw2# debug icmp trace
ICMP trace on
Warning: this may cause problems on busy networks
macaefw2# 102: ICMP echo-request from outside:172.24.16.5 to 172.24.16.8 ID=56 seq=0 length=80
103: ICMP echo-request: untranslating outside:172.24.16.8 to inside:10.10.10.175
104: ICMP echo-request from outside:172.24.16.5 to 172.24.16.8 ID=56 seq=1 length=80
105: ICMP echo-request: untranslating outside:172.24.16.8 to inside:10.10.10.175

From the sh log enabled i do see
--------------------------------

605005: Login permitted from 172.22.20.142/3876 to outside:172.24.16.7/ssh for user "acergy"
111008: User 'enable_15' executed the 'debug icmp trace' command.
106100: access-list acl_outside permitted icmp outside/172.24.16.5(0) -> inside/172.24.16.8(8) hit-cnt 1 (first hit)

Also doing sh Xlate i see
---------------------------

1 in use, 1 most used
Global 172.24.16.8 Local 10.10.10.175

The full configuration is below. Can you please tell me why ping does not work?
