DHCP address pool addres of USG2200 base on global is not enough for using.
The USG2200 connects with switch, which of 192.168.1.1 -192.168.1.200 192.168.1.250 -192.168.1.254,
These two address manually assigned.
192.168.1.201-192.168.1.249 is automatically assigned
The configuration is as follows:
dhcp server forbidden-ip 192.168.1.1 192.168.1.200
dhcp server forbidden-ip 192.168.1.250 192.168.1.254
dhcp server ip-pool first
network 192.168.1.0 mask 255.255.255.0
ip address 192.168.1.1 255.255.255.0
Due to an increase in laptop users, 192.168.1.201-192 .168.1.249 these address are already not enough
Customers need to know the solutions
There are two ways:
Expand mask such as 255.255.255.0 24-bit mask to expand into 255.255.0.0 16-bit mask
But this change is relatively large, the following must be manually changed to 16 bit mask
2. Make another address pool, interface primary address configured to address in this segment such as:
dhcp server ip-pool abc
Address 192.168.2.0 mask 255.255.255.0 is used for users who need automatically assigned address
Ip address 192.168.2.1 255.255.255.0 192.168.2.1 configured as the primary address, previous 1.1 configuration sub address, selected address pool is associated with the main address, such as the main address is 192.168.2.1, the allocation would choose 2 segment for allocating.
ip address 192.168.1.1 255.255.255.0 sub
Automatically assigned address is the segment 2 address, fixed allocation for 1 network segment address to meet customer needs.
