Ping responding from from localhost ?!

[tryllz]

Hi,

I have the following network setup.

1st Firewall
Firewall Interface - 192.168.10.3 / 24
Default Gateway - 192.168.10.2 / 24
Static Route - 10.0.64.0/27

2nd Firewall
Firewall Interface - 192.168.10.7 / 24
Default Gateway - 192.168.10.6 / 24
DNS - 192.168.10.2 / 24
Static Route - 192.168.28.0/27

When I perform Firewall > Interfaces > Trace Route or Firewall > Interfaces > Trace Route from 2nd Firewall to 1st Firewall's connected interfaces I receive a response from 2nd Firewall's localhost and I'm confused as to why.

Any thoughts, thank You.
