Method used to increase the number of IP addresses that can be allocated in the current network segment on the USG firewall

On the USG2000, USG5000, and USG6000, you can increase the number of IP addresses that can be allocated in the current network segment as follows:
You can increase the number of IP addresses in two ways:
1. Expand the mask.
For example, expand 24-bit mask 255.255.255.0 to 16-bit mask 255.255.0.0.
a. For dynamic address allocation, modify the mask in the address:
[FW]dhcp server ip-pool pool1
[FW-dhcp-pool1]gateway-list 10.1.1.1
[FW-dhcp-pool1]network 10.1.0.0 mask 16
b. If PCs on the network adopt static IP addresses, modify the mask on each PC.
2. Add a network segment.
This method involves the entire network, especially the route configuration, to enable the new network segment to interwork with the original network segment.
