30.2.2 Configuring a TCP/IP Filter Rule
This section shows you how to configure a TCP/IP filter rule. TCP/IP rules allow you to base
the rule on the fields in the IP and the upper layer protocol, for example, UDP and TCP
headers.
To configure TCP/IP rules, select TCP/IP Filter Rule from the Filter Type field and press
[ENTER] to open Menu 21.1.1.1 - TCP/IP Filter Rule, as shown next.

FIELD
DESCRIPTION
Active
Press [SPACE BAR] and then [ENTER] to select Yes to activate the filter rule or No
to deactivate it.
IP Protocol
Protocol refers to the upper layer protocol, for example TCP is 6, UDP is 17 and
ICMP is 1. Type a value between 0 and 255. A value of 0 matches ANY protocol.
IP Source Route Press [SPACE BAR] and then [ENTER] to select Yes to apply the rule to packets
with an IP source route option. Otherwise the packets must not have a source route
option. The majority of IP packets do not have source route.
Destination
IP Addr
Enter the destination IP Address of the packet you wish to filter. This field is ignored
if it is 0.0.0.0.
IP Mask
Enter the IP mask to apply to the Destination: IP Addr.
Port #
Enter the destination port of the packets that you wish to filter. The range of this field
is 0 to 65535. This field is ignored if it is 0.
Port # Comp
Press [SPACE BAR] and then [ENTER] to select the comparison to apply to the
destination port in the packet against the value given in Destination: Port #.
Options are None, Equal, Not Equal, Less and Greater.
Options are None, Equal, Not Equal, Less and Greater.
