25.5.4 Example 4: NAT Unfriendly Application Programs

Some applications do not support NAT Mapping using TCP or UDP port address translation. In
this case it is better to use Many-to-Many No Overload mapping as port numbers do not

following figure illustrates this.

)

Other applications such as some gaming programs are NAT

unfriendly because they embed addressing information in the data
stream. These applications won’t work through NAT even when using
One-to-One and Many-to-Many No Overload mapping types.

Follow the steps outlined in example 3 to configure these two menus as follows.
