P-791R v2 Support Notes
 
Some servers providing Internet applications such as some mIRC servers do 
not allow users to login using the same IP address. In this case it is better to 
use Many-to-Many No Overload or One-to-One NAT mapping types, thus each 
user login to the server using a unique global IP address. The following figure 
illustrates this. 
     
One rule configured for using Many-to-Many No Overload mapping type is 
shown below. 
 
We can also do this by configure threeOne-to-One mapping type rules. 
9.  Using the Dynamic DNS (DDNS) 
•  What is DDNS? 
The DDNS service, an IP Registry provides a public central database where 
information such as email addresses, hostnames, IPs etc. can be stored and 
retrieved. This solves the problems if your DNS server uses an IP associated 
with dynamic IPs.
