7.5. NAT Setting
NAT (Network Address Translation) allows hosts in an organization’s private
intranet to transparently connect to hosts in the public domain. There is no
need for internal hosts to have registered Internet addresses. It is a way to
translate the internal private network IP address into a legal network IP
address technology. The NAT in the device web is limited to maintaining a
connection with the remote SIP server. The principle is to send a heartbeat
message to the remote SIP server at a set interval after the function is turned
on. Otherwise, the server may judge that the device is offline and allocate the
SIP assigned to other devices, resulting in failure to connect to it in the future.
