10/100 8-Port VPN Router
for the Remote Management setting, and enter the port
number (port
80
, the default, or 8080 is usually used).
NOTE:
If the Remote Management feature on
the
Firewall > General
screen has been enabled,
then users with administrative privileges can
remotely access the web-based utility. Use
http://<WAN IP address of the Router>
, or
use
https://<WAN IP address of the Router>
if
you have enabled the HTTPS feature.
HTTPS
HTTPS is a secured HTTP session. If Remote
Management is enabled, HTTPS is enabled by default.
NOTE:
If you disable the HTTPS feature, then
you also disable the Linksys QuickVPN service
on the Router.
Multicast Pass Through
This option is disabled by default.
IP multicasting occurs when a single data transmission
is sent to multiple recipients at the same time. Using
this feature, the Router allows IP multicast packets to be
forwarded to the appropriate LAN devices. Multicast Pass
Through is used for Internet games, videoconferencing,
and multimedia applications.

Firewall > Access Rules
Access rules evaluate network traffic to decide whether
or not it is allowed to pass through the Router’s firewall.
Access Rules look specifically at a data transmission’s
source IP address, destination IP address, and IP protocol
type, and you can apply each access rule according to a
different schedule.
With the use of custom rules, it is possible to disable all
firewall protection or block all access to the Internet, so
use extreme caution when creating or deleting access
rules.
The Router has the following default rules:
All traffic from the LAN to the WAN is allowed.
•
All traffic from the WAN to the LAN is denied.
•
All traffic from the LAN to the DMZ is allowed.
•
All traffic from the DMZ to the LAN is denied.
•
All traffic from the WAN to the DMZ is allowed.
•
All traffic from the DMZ to the WAN is allowed.
•
Custom rules can be created to override the above default
rules, but there are four additional default rules that will
be always active and cannot be overridden by any custom
rules.
HTTP service from the LAN to the Router is always
•
allowed.
DHCP service from the LAN is always allowed.
•
DNS service from the LAN is always allowed.
•
Ping service from the LAN to the Router is always
•
allowed.
