Usage guidelines
Connection requests initiated from the CPE can reach the ACS through a NAT gateway without NAT
traversal. However, for the connection request initiated from the ACS to reach the CPE, you must
enable NAT traversal on the CPE when a NAT gateway resides between the CPE and the ACS.
The NAT traversal feature complies with Simple Traversal of UDP Through NATs (STUN), RFC 3489.
The feature enables the CPE to do the following:
•
Discovers the NAT gateway.
•
Obtains an open NAT binding (a public IP address and port binding) through which the ACS can
send unsolicited packets.
The CPE sends the binding to the ACS when it initiates a connection to the ACS. For the connection
requests sent by the ACS at any time to reach the CPE, the CPE maintains the open NAT binding.
