Example 3: Menu 15.2.1

7.5.4 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.
