Configure a Filter Rule-IP Filters
You can limit access to the WAN from PCs on your LAN, or limit
access from the WAN to your LAN using filter rules that can be
configured on your UT-300R2 ADSL router. The UT-300R2
router will examine incoming and outgoing packets to determine
if they meet the requirements you specify in the Filter rule, and
then either
Allow
or
Deny
access based upon the rule you
have configured. These rules can be based on IP addresses,
MAC addresses, URLs, Domain names, and TCP/UDP port
numbers. In addition, you can specify a rule to apply to packets
from your LAN to the WAN (Internet), from the WAN to your
LAN, or both.
To configure a filter rule, click on the
Filter
button under the
Advanced
tab. This will open the
Filters
page, as shown below.
