Figure 190 – Add New Firewall Rule
Target – this implementation of firewall control supports two types of rules – Accept and Drop. The
appropriate policy defines what to do if the data packet received matches the rule.
Source IP Address – source IP address.
Source Netmask – source netmask IP address.
Source Port(s) – can be specified in two ways: "All" or a given port range.
Destination IP Address – specified the same as Source IP.
Destination Netmask – specified the same as source netmask.
Destination Port(s) – specified the same as Source port.
Protocol – network protocol, which affects the rule. Can be specified as one of TCP/UDP/ICMP or
"any".
ICMP Type – if ICMP network protocol is selected, then the appropriate protocol type can be chosen.
Leave the Source/Destination IP and Netmasks fields empty if you want to specify it
as "any".
