DESCRIPTION
Press [SPACE BAR] and then [ENTER] to select Yes to activate
the filter rule or No to deactivate it.
Protocol refers to the upper layer protocol, e.g., TCP is 6, UDP is
17 and ICMP is 1. Type a value between 0 and 255. A value of 0
matches ANY protocol.
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.
Enter the destination IP Address of the packet you wish to filter.
This field is ignored if it is 0.0.0.0.
Enter the IP mask to apply to the Destination: IP Addr.
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.
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 #.
Enter the source IP Address of the packet you wish to filter. This
field is ignored if it is 0.0.0.0.
Enter the IP mask to apply to the Source: IP Addr.
Enter the source 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.
Press [SPACE BAR] and then [ENTER] to select the comparison
to apply to the source port in the packet against the value given
in Source: Port #.
This field is applicable only when the IP Protocol field is 6, TCP.
Press [SPACE BAR] and then [ENTER] to select Yes, to have
the rule match packets that want to establish a TCP connection
(SYN=1 and ACK=0); if No, it is ignored.
Press [SPACE BAR] and then [ENTER] to select Yes or No. If
Yes, a matching packet is passed to the next filter rule before an
action is taken; if No, the packet is disposed of according to the
action fields.
If More is Yes, then Action Matched and Action Not Matched
will be N/A.
