STUN Config
STUN stands for "Simple Traversal of UDP through NATs". STUN enables a device to find out its public IP address and the type of NAT
service it is sitting behind.
STUN is most commonly used with older modems under ACS management connected via a NAT gateway. NAT accommodates a LAN-
side device that has been allocated a Private IP address such as a CPE device on a private network behind an ONT. In this instance,
the regular CWMP Connection Request mechanism to talk to the modem gateway cannot be used to initiate a session with that ACS.
A STUN server receives STUN requests and sends STUN responses. STUN servers are generally attached to the public Internet.
On this page, when a STUN server is present within the infrastructure of the Service Provider, you can configure this gateway with
the connectivity specifics for that server.
