Figure 26: Packet Filter Initial Window
The Outbound filter applies on all outbound packets. The Inbound filter
applies only on packets that are destined to Virtual Servers or DMZ host.
You can select one of the following filtering policies:
 Allow all to pass except those match the specified rules
 Deny all to pass except those match the specified rules
You can specify up to 8 rules for each direction, inbound and outbound.
For each rule, you can define the following:
 Source IP address – You can define a single IP address (4.3.2.1) or a
range of IP addresses (4.3.2.1-4.3.2.254). An empty field denotes all
IP addresses.
 Source port address - You can define a single port (80) or a range of
ports (1000-1999). Add prefix "T" or "U" to specify a TCP or UDP
protocol. For example, T80, U53, U2000-2999. No prefix indicates
both TCP and UDP protocols. An empty field denotes all port
addresses.
 Destination IP address - You can define a single IP address (4.3.2.1)
or a range of IP addresses (4.3.2.1-4.3.2.254). An empty field
denotes all IP addresses.
 Destination port address - You can define a single port (80) or a
range of ports (1000-1999). Add prefix "T" or "U" to specify a TCP or
UDP protocol. For example, T80, U53, U2000-2999. No prefix
indicates both TCP and UDP protocols. An empty field denotes all
port addresses.
