Abstract
An authentication relay and a NAT module of a telecommunication system facilitate communication between authentication clients and an authentication server. The authentication relay identifies authentication messages from the authentication clients intended for the authentication server. The authentication relay repackages the identified authentication message to add additional information. The NAT module translates the private IP address and UDP port number of the authentication client included in the original authentication message into a public IP address and unique UDP port number included with the repackaged authentication message sent to the authentication server. The same public IP address is used for authentication messages from a plurality of authentication clients thereby reducing the number of IP addresses required by the system. When a reply message is received from the authentication server, the NAT module uses the unique port number in the reply message to readdress the reply message for the authentication client.
