i know i need a NAT to map the address of MCU, but i want to know which port i should open .... the NAT is work on a firewall

Well, that depends....You need to be a bit more specific about the MCU you are using.

However, simple NAT generally doesn't work for VoIP/Video as the source and destination addresses are embedded within the data packets. You usually need something a bit cleverer to do a full protocol re-write. e.g. Cisco CUBE or VCS-X

Hi,

You can also get it to work buy enabling the second NIC port on the MCU (this requires an additional license). That port is dedicated for that issue.You can then connect the second port to the Internet/DMZ.
