So.. I have a hard coded IP address of a system, whos DNS is not pointing to any valid address (172.16.16.1.. which is also set as the GW address of the device).

Can (and if so.. how)... translate that via policy on the Sonicwall (tz215) to take that DSN 172.16.16.1 and translate it to something valid.. ala 8.8.8.8 ?

Thank you

You *might* be able to do a NAT policy that would translate while going across zones (assuming that zones are being crossed), but I honestly do not think that it would work. I'm assuming the the gateway address that's been hardcoded is the IP address of the Sonicwall, which cannot handle DNS duties.

So it would be a NAT policy saying that basically says this (assuming that 172.16.16.5 is the IP of the system in question, and 8.8.8.8 is the DNS server you truly wanted to use):

Source                                           Destination                               Service
Original            Translated          Original             Translated      Original    Translated
172.16.16.5      [Public IP]           172.16.16.1       8.8.8.8             DNS           Original


The example I put in would be a LAN > WAN NAT policy for the interface that the device is connected on.
