Issue Description
What Are Differences of Easy IP and Address Pool?
Solution
Easy IP uses the public IP address of an interface as the translated source address, as shown in Figure 1.

When the address pool mode is used, you need to configure a public address pool from which public addresses mapping private addresses are selected, as shown in Figure 2.

Use Easy IP or address pool according to planning of public IP addresses:
  • If there are idle public IP addresses after IP addresses of outbound interfaces on NAT devices and other applications are configured, use the address pool mode.
  • If there are no idle public IP addresses after IP addresses of outbound interfaces on NAT devices and other applications are configured, use Easy IP.
