28.4.4 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-One-to-One mapping as port numbers do not change for
Many-One-to-One (and One-to-One) NAT mapping types. The 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-One-to-One mapping types.
