6.5 IP Filter
6.5.1 Aims:
The IP filter function is working like a simple firewall. Users can set up policies per ATM channel to allow/deny the data
transfer to/from a certain IP address, or TCP/UDP port number. The IP filter should be used to give basic firewall capability
when not using NAT.
6.5.2 Procedures:
<Channel Configuration>
Before IP Filter Configuration starts, there MUST be at least one routing channel defined in Quick Setup/Channel and you
must check the IP Filter box in Channel Setup. check to enable the IP filter function for the channel.
<IP Filter Configuration Menu>
The <IP Filter> function can be found under <Network Service>. The IP filter configuration is independent in each channel,
so, users may define different group or set of groups to each channel. A channel may have up to 16 groups.
Channel No
The number of the ATM channel to be set up; normally this would be one
Groups
The policies to be ADDed or DELETEd for the channel. Users can type one or more groups or a range of groups. For
example, "0-2,4-5" means all Groups 0, 1, 2, 4, and 5 are included.
ADD
To add one or more pre-defined Groups to the channel. The new configuration will work immediately but NOT be
remembered after a router restart unless you do a SAVE (see below).
DELETE
To remove one or more Groups from the channel. The new configuration will work immediately but NOT be remembered
after a router restart unless you do a SAVE (see below).
