MAX NAT
connection to
the host
In this field, enter the maximum number of concurrent NAT connection for each
client device.
If applications like P2P uses only a few applications, you can use this number to increase to
achieve higher download speeds. However, if a lot of these applications, it is recommended to
reduce this number to prevent the depletion of available NAT connection.

Gateway SIP ALG allows SIP redirect calls through the NAT data stream through NAT. After registration LTE
modem for SIP server, SIP ALG gateway translates a private IP address LTE modem inside the SIP data
stream to a public IP address. After activating the SIP ALG gateway eliminates the need to use any
communication STUN or outbound proxy.
In an LTE network can easily be overloaded LTE interfaces for sending repeated requests for registration with the
SIP server because of a timeout session. The default timeout connection with NAT (3600 seconds) reduces the
likelihood of overload.
