Filtering Commands ⊕add filter <1-8>

Description: This command adds or modifies the nth IP filter rule in the system

Packet Filtering allows each IP packet exiting a router interface to be examined for a match with a

configured set of rules. If all of the conditions in any rule do not match the contents of the packet, then

the packet is either forwarded or discarded, depending upon the filter default for that interface.

Otherwise, the exception action is taken, i.e., the packet is discarded or forwarded, the opposite of the

default action. The default action for an interface is set by the set filter default command described

below.

The total number of rules system-wide in this version of the firmware is limited to eight. Each of these

rules may be assigned to one specific interface.

The conditions that may be specified are:

Conditions Values

IP Protocol 1. Any Protocol

2. TCP

3. UDP

4. ICMP

5. IGMP

Source IP Address 1. Any value (wildcard)

2. Individual IP Address (xxx.xxx.xxx.xxx)

3. Range of consecutive IP Addresses

(xxx.xxx.xxx.xxx-yyy.yyy.yyy.yyy)

4. A Network of IP Addresses (and its associated subnet mask).

(xxx.xxx.xxx.xxx/mmm.mmm.mmm.mmm)

Destination IP Address 1. Any value (wildcard)

2. Individual IP Address (xxx.xxx.xxx.xxx)

3. Range of consecutive IP Addresses

(xxx.xxx.xxx.xxx-yyy.yyy.yyy.yyy)

4. A Network of IP Addresses (and its associated subnet mask).

(xxx.xxx.xxx.xxx/mmm.mmm.mmm.mmm)

Source TCP/UDP Port 1. Any value (wildcard)

2. A TCP or UDP Port Number

3. A consecutive range of TCP/UDP Port Numbers

Destination TCP/UDP Port 1. Any value (wildcard)

2. A TCP or UDP Port Number

3. A consecutive range of TCP/UDP Port Numbers

Filter is specified by a number.

Note: Incorrect or mistyped filtering entries may cause undesired or unpredictable

behavior. It is strongly recommended that this feature be used with the utmost care and
