CDRouter Support

What are the different types of NAT that are supported?

knowledge-base version 13.3

The type of NAT implemented by the device under test (DUT) plays a significant role in defining its behavior. CDRouter will automatically skip and/or run tests based on the NAT implementation of the DUT. CDRouter supports three different NAT modes:

testvar natMode address-restricted
testvar natMode port-restricted
testvar natMode full-cone

NOTE: Support for full-cone NAT was added in CDRouter 3.7.

A good explanation of the different types of NAT can be found at
