Problem with no nat after upgrade version

Question

Hello Guys...
Im having problems with nat after upgrade....
source = 10.11.7.14
destination = 10.0.32.10
the next hop for 10.0.32/24 is 10.0.5.1, by inside interface. My firewall Pings this 10.0.5.1. When I change the router to doesnt pass by firewall, the connection works from source to destination, works!
In log, im receiving this message:

In 8.2 I had this NAT:
DMZ interface:
Exempt     10.0.32.0/24     10.11.7.0/24     (outbound)
I have a bypass for those networks and services. I guess I dont need bypass because the packet comes from dmz and goes to inside, right? Anyway, I removed bypass and nothing happen!
And now, in 8.4(5) I have:
DMZ     Inside     obj-10.11.7.0/24     obj-10.0.32.0/24     any      original     original    
What can be my problem?

Answer 1

route, look:
Before:
route inside 10.0.32.0 255.255.255.0 10.11.5.1 1
Now and working:
route inside 10.0.32.0 255.255.255.0 10.11.2.3 1
I dont have an interface in the 10.11.5.0 network. I guess when someone configured the route, put this 10.11.5.1 as gateway, but I dont know how it was working.
Now, I changed to 10.11.2.3 and OK. My firewall has an interface in 10.11.2.0 newtork.
But the bypass is a mistery to me yet!
