[Description]
Often we receive a call or e-mail from customers requesting information about what port they need to open to access our devices remotely.
[Solution]
If you want to allow MGate to use a private IP behind your NAT/firewall, you should use the NAPT protocol to map the Public IP to the MGate's private IP in your NAT router. Most routers/firewalls support this function.
For example, you configure the MGate's private IP as 192.168.1.1, and the NAT router's public IP is 61.x.x.x. Next, you should map TCP/UDP port numbers.
The following table lists the most common ports needed for different functions on our gateway products:
