ProSAFE Dual WAN Gigabit WAN SSL VPN Firewall FVS336Gv3
To further narrow down the content filtering, you can configure groups to which the
content-filtering rules apply and trusted domains for which the content-filtering rules do not
apply.
Source MAC Filtering
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. For information about how to use
this feature, see
Enable Source MAC Filtering on page 314.
Features That Increase Traffic
The following sections provide information about features of the VPN firewall that might
cause the traffic load on the WAN side to increase:
LAN WAN Inbound Rules and DMZ WAN Inbound Rules — Port Forwarding
Port Triggering
DMZ Port
Exposed Hosts
VPN, L2TP, and PPTP Tunnels
LAN WAN Inbound Rules and DMZ WAN Inbound Rules — Port Forwarding
Any inbound rule that you create allows additional incoming traffic (from WAN to LAN and
from WAN to the DMZ) and therefore increases the traffic load on the WAN side.
If you have not defined any LAN WAN inbound rules, only the default rule applies, which
blocks all access from outside except responses to requests from the LAN side.
WARNING:
Incorrect configuration of inbound firewall rules can cause serious
connection problems.
Each of the following rules 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
This section summarizes the various criteria that you can apply to inbound rules and that
might increase traffic. For more information about inbound rules, see
Inbound Rules — Port
Forwarding on page 217. For detailed information about how to configure inbound rules, see
