Ip Filtering - Paradyne Hotwire 6321/6322 IDSL Router User Manual

Configuring the DSL Router

IP Filtering

3-8
The DSL router can filter out IP packets.
NOTE:
All Hotwire DSL Router filters are configured on the Hotwire DSL Card.
By default, filtering is disabled on the Hotwire DSL Card for the DSL router.
If enabled, filtering provides security advantages on LANs by restricting traffic on
the network and hosts based on the IP source and/or destination addresses.
IP packets can be filtered based on:
H
Destination IP Address
H
IP Protocol Type
H
Source and Destination Port Number (if applicable)
H
Source IP Address
H
TCP Filter (prevents the receipt of downstream TCP connect requests)
NOTE:
If the Source IP Address filter is enabled on the Hotwire card and an
IP address is assigned to the DSL interface, there must also be an entry
configured in the Hotwire Client Table for the DSL interface's IP address.
For more information about IP filtering, see the Hotwire MVL, RADSL, IDSL, and
Packet SDSL Cards, Models 8310/8312, 8510/8373/8374, 8323/8324, and
8343/8344, User's Guide.
