Netgear FVS318N Manual Do Utilizador

If you want to reduce outgoing traffic by preventing Internet access by certain computers on 
the LAN, you can use the source MAC filtering feature to drop the traffic received from the 
computers with the specified MAC addresses. By default, this feature is disabled; all traffic 
received from computers with any MAC address is allowed. See 

on page 183 for the procedure about how to use this feature.

Features That Increase Traffic

The following features of the wireless VPN firewall tend to increase the traffic load on the 
WAN side:

LAN WAN inbound rules (also referred to as port forwarding)

DMZ WAN inbound rules (also referred to as port forwarding)

Port triggering

Enabling the DMZ port

Configuring exposed hosts

Configuring VPN tunnels

The LAN WAN Rules screen and the DMZ WAN Rules screen list all existing rules for 
inbound traffic (from WAN to LAN and from WAN to the DMZ). Any inbound rule that you 
create allows additional incoming traffic and therefore increases the traffic load on the WAN 
side.

ON the LAN WAN screen, if you have not defined any rules, only the default rule is listed. The 
default LAN WAN inbound rule blocks all access from outside except responses to requests 
from the LAN side. 

Each rule lets you specify the desired action for the connections covered by the rule:

BLOCK always 

BLOCK by schedule, otherwise allow 

ALLOW always 

ALLOW by schedule, otherwise block 

The following section summarizes the various criteria that you can apply to inbound rules and 
that might increase traffic. For more information about inbound rules, see 

on page 133. For detailed procedures about how to configure inbound
