Network Address Translation (NAT) 22-13
Example 3: Menu 15.2.1
22.5.4 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
change for Many-to-Many No Overload (and One-to-One ) NAT mapping types. The
following figure illustrates this.
Figure 22-19 NAT Example 4
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.
