Can't Ping OPT2 Interface IP

[Wasca]

Hi Guys

I have 2 WANS one static IP one PPPoE

I have a public subnet on my OPT2 interface. I have servers on this public network and I can't ping the IP address of the OPT2 interface from this public subnet all I get is this

Pinging 203.xxx.xxx.xxx with 32 bytes of data:
Reply from 203.xxx.xxx.aaa: TTL expired in transit.
Reply from 203.xxx.xxx.aaa: TTL expired in transit.
Reply from 203.xxx.xxx.aaa: TTL expired in transit.

Where 203.xxx.xxx.aaa is my upstream gateway IP

I have the following rule on my OPT2 interface

ICMP  | OPT2 Subnet |  *  |  OPT2 IP |  *  |  *  |

What is happening? why am I getting a response from my upstream gateway IP and not directly the from OPT2 interface

Do not set the source to Opt2 subnet but any and from the 'Destination' dropdown box use "OPT2 address".
