Starting with PIX 5.2, the firewall no longer uses network addresses or broadcast addresses in static and global command statements when creating NAT xlate translations. Broadcast addresses are those addresses with the bit pattern of all ones, when the network mask is applied. Network addresses are those addresses with the bit pattern of all zeros, when the network mask is applied.
global 1 10.1.0.0-10.1.255.255 netmask 255.255.255.0.
With this command, the network addresses 10.1.0.0, 10.1.1.0, 10.1.2.0, and so forth through 10.1.255.0, are excluded. In addition, the broadcast addresses 10.1.0.255, 10.1.1.255, 10.1.2.255, and so forth through 10.1.255.255, are excluded.
