Network Address Translation (NAT)

6.5.4 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-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.
Figure 6-21 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-One-to-One
mapping
types.
Follow the steps outlined in example 3 to configure these two menus as follows.
