src_ip

Source IP address.

Syntax

(32-bit dotted-decimal IP address)

Description

Indicates the packet's source IP address (the IP address of the workstation from which the packet originates).

Address ranges can be indicated in conjunction with the srcmask parameter. Only the masked portion of the IP address (corresponding to a one bit in the mask when both are represented in binary) is actually used for comparison; this treated as the IP network number. (The remaining, unmasked, portion is treated as a wildcard.)

A filter rule can thus indicate 'any IP address' by setting the srcmask parameter to 0.0.0.0. (In this case, srcip should also be set to 0.0.0.0 to avoid confusion.)
