Root Cause
 A:
If the public network addresses are insufficient, you can calculate the proportion of private network addresses to public network addresses based on the following policies in the case that the ME60 performs NAT:
1. One NAT public network address can support 30000 ports.
2. Based on experience, each private network address can be used to access 200 ports.
Therefore, the proportion of private network addresses to public network addresses can be set to 150:1.
Considering that each private network address may be used to access more ports in on-peak Internet hours, it is recommended to set the proportion to about 100:1.
