Thanks Farhan ,
ACE is inline , so i expect default destination nat to kick in .
SLB is only done for port 25 .
When I ping 4.2.2.2 source from outside interface it works fine .
When i source ping to 4.2.2.2 servers default gateway it dosent work ,
i have checked routing in my infrastructure and the server subnet is
fully routable.
ACE Version : A4(2.0)
