IP Filtering Outgoing
IP filtering enables you to configure your router to block specified internal/external users (
IP address
)
from Internet access, or you can disable specific service requests (
Port number
) to /from Internet.
The relationship among all filters is
“or”
operation, which means that the router checks these
different filter rules one by one, starting from the first rule. As long as one of the rules is satisfied, the
specified action will be taken.
Outbound IP Filtering by default is set to
forward
all outgoing traffic from LAN to go through the
router, but user can set rules to
block
the specific outgoing traffic.
Note:
The maximum number of entries: 32.

Filter Name:
A user-defined rule name. User can select simply from the list box for the application
for quick setup.
IP Version:
Select the IP Version, IPv4 or IPv6.
Protocol:
Set the traffic type (TCP/UDP, TCP, UDP, ICMP ) that the rule applies to.
Source IP address:
This is the Address-Filter used to allow or block traffic to/from particular IP
address(es) featured in the IP range. If you leave empty, it means any IP address.
Source Port [port or port:port]:
The port or port range defines traffic from the port (specific
application) or port in the set port range blocked to go through the router. Default is set port from
range 1 – 65535.
Destination IP address:
Traffic from LAN with the particular traffic destination address specified in
the IP range is to be blocked from going through the router, similarly set as the Source IP address
above.
