Sonicwall NSA 4500 and Odd NAT policy issues

Posted on 2011-10-19

OK - I have something that seems odd going on here.  I have a computer with and internal IP address with a NAT policy to allow incoming connections over a public IP.  

So, these have always seemed to work out OK.  Now, if I attempt to ping the server, from an internal PC, within the same subnet, the replies are returned from the Public IP address.  This doesn't matter if I ping from a hostname or even IP address - it always gives replies coming from the public NAT address.  As far as i can tell this is only happening with a single unit.

Note, I am using the Enhanced OS, as well as creating reflexive NAT polices in the NSA

Note that the internal ip will respond with the external ip on a one to one reflective nat.
