What Are Differences of Easy IP and Address Pool?
Easy IP uses the public IP address of an interface as the translated source address, as shown in Figure 5-34.
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 5-35.
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.
