Pool Size Enter the number of IP addresses to allocate. This number must be at
least one and is limited by the interface’s
Subnet Mask
. For example,
if the Subnet Mask is 255.255.255.0 and IP Pool Start Address is
10.10.10.10, the ZyWALL can allocate 10.10.10.10 to 10.10.10.254,
or 245 IP addresses.
If this field is blank, the ZyWALL can assign every IP address allowed
by the interface’s IP address, subnet mask, and IP Pool Start
Address
; except for the first address (network address), last address
(broadcast address) and the interface’s IP address.

the IP address) before it has to request the information again. Choices
