Port Management
Configuring the Port Settings
Cisco Small Business RV0xx Series Routers Administration Guide

For Cisco RV016 only, choose the number of WAN ports from the drop-down list,
or keep the default number, 2. If you change the number, save your settings. (You
can also change the number of WAN ports by using the
Setup > Network
page.)
The following read-only information is displayed for each port:
•
Port ID:
The port number or name, as it is labeled on the device
•
Interface:
The interface type: LAN, WAN, or DMZ
Enter the following settings, as needed:
•
Disable:
Check this box to disable a port. By default, all ports are enabled.
•
Priority
(for LAN ports only)
:
Use this setting to ensure Quality of Service
by prioritizing the traffic for devices on particular ports. For example, you
might assign High priority to a port that is used for gaming or
videoconferencing. For each port, select the appropriate priority level,
High
or
Normal
. The default setting is Normal.
•
Speed:
If you want to adjust this setting, first uncheck the
Enable
box in the
Auto Neg
column to disable auto-negotiation. Then select the port speed:
10M
or
100M
.
•
Duplex:
If you want to set the duplex mode, first uncheck the
Enable
box in
the
Auto Neg
column to disable auto-negotiation. Select the duplex mode,
Half
or
Full
.
•
Auto Neg.:
Check the
Enable
box to allow the router to auto-negotiate
connection speeds and duplex mode. This feature is enabled by default.
•
VLAN
(for LAN ports only)
:
All LAN ports are on VLAN 1 by default. To place
a port on a separate VLAN, choose a VLAN from the drop-down list.
The number of available VLANs equals the number of LAN ports: 4 on Cisco
RV042 and RV042G, 8 on Cisco RV082, and up to 13 on Cisco RV016
(depending on the usage of the dual-function ports). For example, on Port 4,
you may have an Ethernet switch that provides Internet connectivity to
guest users in a conference room. To prevent your guests from accessing
the file servers and printers on your LAN, you could put Port 4 on VLAN 2
and leave the other ports on VLAN 1. There is no communication between
devices on separate VLANs.

Firewall
Use the Firewall module to configure the firewall features, create access rules, and
set content filters to control your users’ Internet activities. Refer to these topics:
•
Configuring the General Firewall Settings, page 99
•
Managing Access Rules, page 104
•
Configuring Firewall Access Rules, page 103
•
Using Content Filters to Control Internet Access, page110
Configuring the General Firewall Settings
The default firewall settings should be sufficient for most small businesses.
However, you can use the
Firewall > General
page to disable the firewall or to
specify the types of attacks that you want to block. You also can restrict
potentially risky website features such as Java and cookies.
To open this page:
Click
Firewall > General
in the navigation tree.

NOTE
•
If you want to disable the firewall (not recommended), you can do so only if
you have configured the administrator password. If you are still using the
default password, you must change it. For more information, see
Changing
the Administrator Username and Password, page 40
.

Enable or disable the firewall and related features:
•
Firewall:
Choose to enable or disable the firewall. This feature is enabled
by default and is strongly recommended to protect your network. Enabling
or disabling the firewall also affects several related features, as described
below. Disabling the firewall also disables Access Rules and Content Filters.
If you choose
Disable
and you are still using the default administrator
password, a message appears. To protect your router from unauthorized
access, you must change the password before you can disable the firewall.
Click
OK
to continue to the
Password
page, or click
Cancel
to remain on the
current page. After you change your password, you can return to this page
to resume this procedure.
•
SPI (Stateful Packet Inspection):
When enabled, this feature allows the
router to review the information that passes through the firewall. It inspects
all packets based on the established connection, prior to passing the
packets for processing through a higher protocol layer. This feature can be
enabled only when the firewall is enabled.
•
DoS (Denial of Service):
When enabled, this feature protects internal
networks from Internet attacks, such as SYN Flooding, Smurf, LAND, Ping of
Death, IP Spoofing, and reassembly attacks. This feature can be enabled
only when the firewall is enabled.
•
Block WAN Request:
When enabled, this feature allows the router to drop
both unaccepted TCP requests and ICMP packets from the WAN side.
Hackers will not find the router by pinging the WAN IP address. This feature
can be enabled only when the firewall is enabled.
•
Remote Management:
When enabled, this feature allows you to connect to
the router’s web-based configuration utility through a WAN connection. This
feature is disabled by default. It can be enabled only when the firewall is
enabled. If you want to enable remote management, you should first
configure a strong administrator password on the
Setup > Password
page.
This precaution prevents an unauthorized user from accessing the router
with the default password. If you enable this feature, you can keep the

Rate

4 / 5 based on 1 vote.
