• netmask for a single computer: 255.255.255.255, or /32
• netmask for a class A subnet: 255.0.0.0, or /8
• netmask for a class B subnet: 255.255.0.0, or /16
• netmask for a class C subnet: 255.255.255.0, or /24
• netmask including all IP addresses: 0.0.0.0
Valid IP address and netmask formats include:
• x.x.x.x/x.x.x.x, such as 192.168.1.0/255.255.255.0
• x.x.x.x/x, such as 192.168.1.0/24
When representing hosts by an IP range, the range indicates hosts with continuous IP
addresses in a subnet, such as 192.168.1.[2-10], or 192.168.1.* to indicate the
complete range of hosts on that subnet. Valid IP range formats include:
• x.x.x.x-x.x.x.x, such as 192.168.110.100-192.168.110.120
• x.x.x.[x-x], such as 192.168.110.[100-120]
• x.x.x.*, such as 192.168.110.*
Configuring WAN optimization peers
You can add the local host ID that identifies the FortiGate unit for WAN optimization and
add the peer host ID and IP address of each FortiGate unit with which a FortiGate unit can
create WAN optimization tunnels.
To configure WAN optimization peers, go to WAN Opt. & Cache > Peer.
Figure 428: WAN optimization peer list
Note: An IP address 0.0.0.0 with netmask 255.255.255.255 is not a valid source or
destination address.
