We have a simple basic setup:
WAN1/1 Untrust IP 22.214.171.124/29
LAN1/2 Trust IP 10.9.8.1/16
We NAT our WAN interface out to a different IP in the same network. 126.96.36.199
NAT POL Trust to Untrust Int1/1 Any Any to 188.8.131.52
Security Pol is Any Any
I ping 184.108.40.206 from the LAN1/1 and it NATs out correctly with the .90 address
Devices behind the firewall are not getting NAT'd out, I have pcap that shows this. The pcap does not show the NAT'd IP just the trust traffic from the device to the LAN1/1 on both outbound and inbound traffic.
I can also ping the ISP GW from the downstream devices so I can get traffic beyond the FW but nothing beyond that.

everything looks ok...
if you start a ping out to the internet, can you check if the session ID of your outgoing ping to see which rules it hits etc:
show session all filter destination 18.104.22.168 application ping
show session id xxx

I can ping the internet from the Trust interface but nothing behind it. My pcap shows ping from the trust interface NATs out correctly but the ping from a the devices behind the FW do not NAT at all. Ping source 10.61.1.1 to host 22.214.171.124 success, Ping source 10.61.1.2 host 126.96.36.199 fails....aged out. Basically no NAT from devices behind the Trust interface.

Strange I updated the OS 9.1.4 to 9.1.5 rebooted and now it is working
