The default configuration on SonicWall TZ 210 security appliances contains two unexpected NAT

Question/Topic:

The default configuration on SonicWall TZ 210 security appliances contains two unexpected NAT policies.

Resolution/Workaround:

Occurs when using the factory defaults on a TZ 210. The appliance is configured with these two NAT policies: "Translate to LAN Primary IP on W0 to X0 traffic" and "Translate to LAN Primary IP on
X0 to X0 traffic."

Upgrading to SonicOS Enhanced 5.1.3.2 or above resolves the issue.
