Tip:
When configuring Easy IP, if the "External IP address" is not on the same network segment as the
IP address of the bound interface, a route must be configured on the upper router to the network
segment on which the "External IP address" resides or a 32-bit host route to the "external IP
address", and the next hop is set to the IP address of the bound interface.

An enterprise applies for a line of Telecom, which adopts the fixed IP access method, and the
bandwidth is 6M. Telecom assigned 8 addresses to it: 202.1.1.128/29-202.1.1.1.135/29. Here,
202.1.1.129/29 is the gateway address of the line, and 202.1.1.130/29 is the IP address of the
device's WAN1. Note: 218.1.21.0/29 and 218.1.21.7/29 are respectively the related subnet number
and broadcast address, which cannot be used.
The company wants its people to access to the Internet via NAT by using 202.1.1.130/29 sharing.
Additionally, there are four servers that are in one-to-one NAT (One2One) and use
202.1.1.131/29-202.1.1.1.134/29 for providing services externally. The internal network address is
192.168.1.0/24, and the address for 4 servers is 192.168.1.200/24-192.168.1.203/24.
