Configuring IP Based ACL
The Firewall > IP Based ACL window displays a summary of the configured
IP-based access control list. The access list restricts traffic going through the
router either from WAN or LAN port.
There are two ways to restrict data traffic. You can block specific types of traffic
according to your ACL definitions. Or you can allow only specific types of traffic
according to your ACL definition. The ACL rules are read according to their priority.
If there is a match for a packet, the action is taken and the following lower priority
rules are not checked against this packet.
The higher the number of rules that need to be checked against packets, the lower
the throughput. Use ACL rules with caution.
There are two default rules in the table that cannot be deleted. The first rule allows
all traffic coming in from LAN port to pass the router. The second rule allows all
traffic coming in from WAN port. These two rules have the lowest priority, so
without adding any user defined rules, all the packets can be passed through from
both WAN and LAN sides. The rule is enabled if the Enable button is checked and
if the date and time are matched. If any of the conditions are not met, the rule is not
used to check against packets.
