any rule for that interface, 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 Wireless Router maintains separate filtering tables for IP and IPX traffic. These
filters are configured separately. Configuration commands allow you to define:
-
each and every IP or IPX packet to be inspected to determine if it should be
allow
ed to be transmitted over a WAN interface alternatively.
-
each and every IP or IPX packet to be inspected to determine if it should be
disallow
ed from being transmitted over a WAN interface alternatively.
Due to the conflicting nature of
allow
and
disallow
, only one of the above two
choices can be made for each WAN interface. After the choice is made, you can
define selection rules to “select” which packets will be allowed (or disallowed).
Each packet selection rule consists of
-
an IP protocol and set of local IP addresses/ports or an IPX Packet Type and
a set of local IPX network number(s), node(s) and socket(s)
-
a set of remote IP addresses/ports or remote IPX network numbers/nodes/
sockets
The following table indicates the types of values that may be configured for each rule
condition.
