Is the NAT ALG Function Applicable to the H.323 Protocol?

Is the NAT ALG Function Applicable to the H.323 Protocol?

No, AR routers cannot implement NAT ALG for H.323 packets.

The NAT ALG function implements NAT for specific application-layer protocols by changing IP addresses and port numbers in data portions of IP packets based on NAT state information. In this way, the application-layer protocol packets can travel across private and public networks. After NAT ALG is enabled for an application-layer protocol, packets of this protocol can pass through the NAT device. Currently, the NAT ALG function is applicable to the FTP, DNS, SIP, PPTP, and RTSP protocols.
