DSL/Cable modem
In a small office, the HP R110/R120 can be directly connected to a broadband modem (DSL or
cable) to provide secure wireless networking for all employees. In the following scenario,
employees can share data and resources with each other and access the Internet at the same
time:
With its wireless community feature, the R110 can be configured to provide up to four separate
wireless networks (all on the same wireless channel), and the R120 up to eight wireless
networks (split between two radios), each with its own configuration settings for security, VLAN
support, and more.
In this scenario, employees connect to wireless community 1, which is protected with WPA/
WPA2. All employee traffic exits the HP R110/R120 on VLAN 1, providing access to private
resources on the company network and on the Internet.
Guests connect to wireless community 2, which is protected with WEP. All guest traffic exits the
HP R110/R120 on VLAN 2, providing access only to the Internet.
For offices that need Ethernet ports for wired connectivity, the R110/R120 has a built-in 4-port
gigabit switch. It can also be used to extend the reach of the network to areas that are difficult
or impossible to reach with Ethernet cabling.

employees in the main office, while HP R110/R120 #2 and HP R110/R120 #3 use the Wireless
Distribution System (WDS) to create a wireless link between the main office network and a
small network in a warehouse. WDS eliminates the need to run cabling, allowing for fast and
easy deployment.
In the following scenario, an HP R110/R120 located in an office provides a virtual private
network (VPN) connection across the Internet to a remote client (typically a mobile worker). The
R110/R120 forms a secure VPN (IPSec, PPTP, L2TP/IPSec) connection to the remote client,
which can then access the computers and servers in the office network. The remote client can
be a Windows or Mac computer, or any Apple iOS or Android mobile device.

2 Using the Wizard Setup
Overview
The Wizard Setup provides an easy way to quickly configure basic settings on the R110/R120
and make the router operational.
Automatically running the Wizard Setup the first time you log in
The first time you log in to the management interface (see the HP R100-Series Wireless VPN
Routers Quickstart for the first time login procedure), the HP end user license agreement
displays. When you accept the agreement, a page displays to enable you to select your
country so that wireless radio settings are configured appropriately. Select the country in which
the router is operating, and then click Save. The first page in the Wizard Setup appears.
Accessing the Wizard Setup after your first login
When you log in subsequent to completing or canceling out of the Wizard Setup, the System
Status page displays by default.
See also the HP R100-Series Wireless VPN Routers Quickstart, which describes the
configuration procedure for a basic wireless network.
Wizard Setup
To start the Wizard Setup, select Home > Wizard Setup, and then click Start.
Step 1: Specify system time settings
The router keeps time by connecting to a Network Time Protocol (NTP) server. This enables the
router to synchronize the system clock to the global Internet. The synchronized clock in the router
is used to record the system log and control client filtering. Select the proper time zone for your
location. The system clock might not update immediately. The router updates the current time
after it has made contact with time servers on the Internet and has received a response.
Alternatively, the system time can be entered manually or imported from the host computer
(copies the system time from the management computer).
Choose either to configure the system time manually or have it automatically configured by an
NTP server. You can also enable support for daylight savings time, if required for your location.
For more information on setting the system time, see
Step 2: Specify WAN settings
The Internet Connection page allows you to set up the router for the type of Internet connection
you have. Before setting up your connection type, have your account information from your ISP
ready.
The router supports five possible connection types. Your ISP can provide you with information
on the correct type for your Internet connection and the parameters that need to be configured.
Select one of the following Connection Types, enter supplementary information as directed by
the wizard, and then click Next to apply the settings. A description of each connection type
follows.
• DHCP: See “Connection Type: DHCP” on page 12.
• Static IP Address: See “Connection Type: Static IP Address” on page 13.
• PPPoE: See “Connection Type: PPPoE” on page 13.
• PPTP: See “Connection Type: PPTP” on page 14.
• L2TP: See “Connection Type: L2TP” on page 14.
Connection Type: DHCP
A dynamic connection type is the most common method used with cable modems. In most
cases, setting the connection type to DHCP is enough to complete the connection to your ISP. If
your ISP also assigns you a Host Name, enter it in the space provide. Do not use these
characters: ` " & ' # \
“System time settings” on page 21.

.
“DHCP IP address” on
Connection Type: Static IP Address
The Static IP Address Connection Type sets the router to operate with a fixed IP address. If your
ISP provides you with a static IP address, subnet mask, and ISP gateway address, enter them in
the spaces provided.
For more information on the WAN Static IP Address Connection Type, see
on page 30
.
“Static IP address”
Connection Type: PPPoE
The Point-to-Point Protocol over Ethernet (PPPoE) is a common WAN protocol that provides a
secure connection between the service provider and the local network. Enter the specific PPPoE
information assigned by your ISP.
For more information on the WAN PPPoE Connection Type, see
“PPPoE” on page 31.
Wizard Setup 13
Connection Type: PPTP
The Point-to-Point Tunneling Protocol (PPTP) is a common WAN protocol used for Virtual Private
Networks (VPNs) that provides a secure connection between the service provider and the local
network. Enter the specific PPTP information assigned by your ISP.
For more information on the WAN PPTP Connection Type, see
“PPTP” on page 33.
Connection Type: L2TP
The Layer 2 Tunneling Protocol (L2TP) is a common WAN protocol used for Virtual Private
Networks (VPNs) that provides a secure connection between the service provider and the local
network. Enter the specific L2TP information assigned by your ISP.
For more information on the WAN L2TP Connection Type, see
“L2TP” on page 34.
14 Using the Wizard Setup
Step 3: Specify wireless settings
The R110 router features a single dual-band radio for 2.4 GHz or 5 GHz operation. The R120
router features two radios, one for 2.4 GHz and one for 5 GHz operation. This means that the
R110 can operate at 2.4 GHz or 5 GHz, but not both at the same time. The R120 can operate
concurrently at 2.4 GHz and 5 GHz.
The R110 router has a single configuration page for 2.4 GHz or 5 GHz operation. The R120
router has separate configuration pages for 2.4 GHz and 5 GHz operation.
Configure the following basic wireless settings before clicking Next.
Radio Band and Radio Mode
Configure the R110 router to operate in the 2.4 GHz band (for 802.11b/g/n) or the 5 GHz
band (for 802.11a/n).
For R110 and R120, select an operating mode. For 2.4 GHz, the 11 b / g / n M i x e d mode is
configured by default. For 5 GHz, 11 a / n M i x e d (R110) o r 11ac/n/a (R120) mode is
configured by default. For more information, see
“Basic wireless settings” on page 46.
Wizard Setup 15
SSID
Enter a unique name to identify your wireless network.
• By default, a wireless community with an SSID of HP1 is defined on the R110.
• By default, two wireless communities with SSIDs of HPT1_2G and HP1_5G are defined
on the R120.
For more information, see
“Basic wireless settings” on page 46.
Note The R110/R120 allows you to create up to four wireless communities per radio.
MAC Authentication, Authentication Mode, and Encryption Type
Configure wireless security for the default wireless community. The R110/R120 has no wi reless
security configured by default. HP recommends that WPA2 be configured for maximum
security. Leaving the Authentication Mode setting as Open or using WEP security is not
recommended.
For more information on wireless security, see
“Configuring wireless security” on page 49.
Step 4: Summary
After you complete the Wizard Setup, the Summary page displays.
Confirm the settings, and then click Finish. The router reboots and the HP R110/R120 is
operational.
16 Using the Wizard Setup
3 Managing the HP R110/R120 system
The HP R110/R120 is managed via its web-based management interface using Microsoft
Internet Explorer 8 or later, Google Chrome v29 or later, or Mozilla Firefox v24 or later. You
can access the HP R110/R120 management tool using either http or https. Using https is
more secure, but you will see a warning because the security certificate is issued by the router
and not a known certificate authority. With https, it is acceptable to choose the option that
allows you to proceed through the security warning.
In a web browser, specify either: http://192.168.1.1 or https://192.168.1.1.
For information on launching the web-based management interface for the first time, see the HP
R100-Series Wireless VPN Routers Quickstart.
Viewing router status
The Status page displays a summary of the router’s key settings. Click Refresh to update the
status.
The Status page includes these items:
Device Information
Shows the router's software version, hardware serial number, host name, device description,
and country selection.
Resource Utilization
Indicates the status of the router's resources, including CPU and memory usage.
Security
Displays the current settings for the Denial of Service (DoS) and Stateful Packet Inspection (SPI)
features.
When a DoS attack or SPI intrusion (a specific host blocked) is detected, an alert symbol ( )
displays on the Security line. If you open the Security section, an alert message next to
DOS or SPI indicates the security violation. Click Alert to view the log details on the
System > Log page. Click Clear to remove the alert message from the status page.
Note The security alert is not supported when the router is operating in Bridge mode.
Wireless
Displays the current settings for the wireless interface, including: radio enable, operating
frequency, mode, channel, SSID, MAC address, authentication, and encryption.
WAN
Displays the WAN connection type, status, and IP address assignment.
LAN
Displays the router's local network IP address, MAC address, and DHCP server status.
USB
Displays the current status of a device attached to the router's USB port.
SNMP
Displays the status of the Simple Network Management Protocol feature.
Setting the operating mode
The System > Mode page configures the operating mode of the router. The router supports
the following operating modes:
• Router Mode: The normal router mode that allows connections between a wired LAN and
wireless clients to the WAN Internet connection, such as a cable or DSL modem. This is the
factory set default mode.
• Bridge Mode: The router operates like an access point, extending a wired LAN to wireless
clients. In this mode there is no WAN configuration, including routing, VPN, NAT, firewall,
and QoS settings; all Internet access features are disabled. In fact, all four LAN ports and
WAN port are bridged together, so the WAN port operates like another LAN port.
18 Managing the HP R110/R120 system
General administration settings
The System > Admin page configures the following settings for the router.
System information (General) settings
Configures settings that help identify the router, including the system name, location, and the
name of a person to contact for administrative purposes. The system name appears on the
banner and login screen. Do not use these characters: ` " & ' # \
Administrator login credentials
Configures the web management interface login username and password. The login user name
and password can be from 6 to 32 alphanumeric and special characters in length. Do not use
these characters: ` " & ' # \
Setting the Country Code
The country of operation, also known as the regulatory domain, determines the availability of
certain wireless settings on the router. When the country is set, the router automatically limits
the available wireless channels and channel width, and adjusts the radio power level in
accordance with the regulations of the selected country.
General administration settings 19
Caution Incorrectly selecting the country can result in illegal operation and can cause harmful
interference to other systems. You must ensure that the router is operating in accordance with
channel, power, indoor/outdoor restrictions, and license requirements for the intended country.
If you fail to heed this caution, you might be held liable for violating local regulatory
requirements.
Configuring web server settings
This section configures access to the web management interface.
HTTP Server
HTTPS Server
The router software includes HTTP and HTTPS functionality to enable communication with your
web browser. Unlike HTTP, HTTPS provides secure communications, using a digital certificate to
encrypt data exchanged between the router and your web browser. HTTP and HTTPS are both
enabled by default.
Session Timeout
Configure the Session Timeout for automatic log out from the web interface. If there is no
activity on the management session for the specified time, then the administrator is
automatically logged off.
Configuring trusted users
When using the trusted users feature, only computers with specified MAC or IP addresses can
access the router's web management interface. All other devices, either LAN or WLAN, cannot
access the web interface. A maximum of five rules can be defined.
20 Managing the HP R110/R120 system
System time settings
Correct system time is important for proper operation of the router, especially when using the
logs to troubleshoot.
Select System > System time to open the System Time page. This page enables you to
configure time server and time zone information.
Set system time
This section displays the current system time. You can configure the time manually, or have it
automatically configured by a Network Time Protocol (NTP) server.
Manually
Select the date, time (in 24-hour notation), and timezone.
Using network time protocol
NTP servers transmit Coordinated Universal Time (UTC, also known as Greenwich Mean Time)
to their client systems. NTP sends periodic time requests to servers, using the returned time
stamp to adjust its clock. The timestamp is used to indicate the date and time of each event in
the system log or syslog messages.
System time settings 21
When you select this option, a field displays for you to specify the time server address. You can
specify the NTP hostname or IP address, although specifying an IP address is not
recommended because it is more likely to change. If you specify a hostname, note the following
requirements:
• It must be between 1 and 63 characters long.
• Uppercase and lowercase characters, numbers, and hyphens are allowed.
• The first character must be a letter (a to z or A to Z), and the last character cannot be a
hyphen.
An actual NTP server host name, pool.ntp.org, is configured by default and will provide the
time when the router is connected to the Internet.
Daylight saving
Use this section to enable support for daylight saving time, if required for your location. When
you select Manually Set Time For Daylight Savings, additional fields display to enable
you to configure the starting and ending dates and times, and the DST offset.
The DST offset specifies how many minutes to move the clock forward or backward.
Configuring SNMP
The Simple Network Management Protocol (SNMP) enables the remote management of the HP
R110/R120 router by a computer that has SNMP management software installed. The HP
R110/R120 provides a robust SNMP v1/v2c implementation supporting both industry-standard
MIB II objects and HP-specific MIB objects. Read-only and read-write access are supported.
Select System > SNMP to open the SNMP configuration page.
22 Managing the HP R110/R120 system
To configure SNMP, set the following options:
• Enable SNMP: Use this checkbox to enable/disable SNMP support. By default, SNMP
support is disabled, which means that the HP R110/R120 does not respond to SNMP
requests.
• Read Community: The password that controls read-only access to SNMP information on
the router. A network management program must supply this password when attempting to
get SNMP information from the router. By default, the password is set to public. Do not use
these characters: ` " & ' # \
• Write Community: The password that controls read/write access to SNMP information
on the router. A network management program must supply this password when attempting
to get or set SNMP information on the router. By default, the password is set to private.
Do not use these characters: ` " & ' # \
The router can also be configured to send status messages to an SNMP server if a problem
occurs on the network. This is done by setting the Trap Receiver option. To configure an SNMP
Trap Receiver, set the following options:
• Trap Receiver IP Address: The IP address on the computer to which the status
messages are to be sent.
• Trap Receiver Port: The port number on the computer to which the status messages are
to be sent.
• Trap Community: The computer network management program must supply this
password to receive the trap messages. Do not use these characters: ` " & ' # \
Managing system logs
The system log is a list of system messages, some of which may indicate error conditions. The
router stores up to 2048 system messages in memory. You can view these messages using the
router’s management interface, and you can configure the router to relay them as syslog
messages to a syslog server residing on the network. Note that the log messages in volatile
memory are lost when the system reboots.
Managing system logs 23
To configure system logging, set the following options:
System Log Level
You can specify the minimum severity level of the log messages to write to the system log. In the
following list, the severity levels are listed from most severe (top) to least severe (bottom):
• Emergency indicates that the system is unusable. It is the highest level of severity.
• Alert indicates action must be taken immediately.
• Critical indicates critical conditions.
• Error indicates error conditions.
• Warning indicates warning conditions.
• Notice indicates normal but significant conditions.
• Informational indicates informational messages.
• Debug indicates debug-level messages.
For example, if you select Critical, only critical, alert, and emergency messages are written to
the log.
Max Size
Specifies the maximum number of log entries to store in the router's volatile memory. When the
maximum number is reached, the old log messages are overwritten by new messages.
Log Prefix
A text identification string that is added to the log messages. This is useful for quickly
identifying messages you are interested in when using a remote syslog server.
Remote Syslog Configuration
To view a longer history of log messages, you can set up a remote syslog server that acts as a
syslog log relay host on your network. Then, you can configure the router to send syslog
messages to the remote server. The System Log Level setting determines which messages are
stored and are available for relay to a remote syslog server.
• IP Address: Specify the IP address of the remote syslog server.
24 Managing the HP R110/R120 system
Events
• Port: The syslog process uses logical port 514 by default. It is recommended that you keep
this default. If you specify a different port number, ensure that the port number is not being
used by another protocol on your network and that your syslog server is also configured to
use that port.
• Log Level: When Remote Syslog is enabled, messages of the selected Log Level or higher
are sent to the configured syslog server.
The Events section of the System log page shows real-time system events on the router, such as
wireless clients associating with the router and being authenticated. The log shows the date the
event occurred, its severity level, the software program or process that caused the event

Proxy ARP settings
Proxy ARP (Address Resolution Protocol) is a mechanism that enables a computer in a network
connected to a router to appear to be logically part of another network connected to the same
router. This means that a computer on the router’s LAN network can appear to be logically on
the WAN network, accessible using a public IP address. Note that although the computer
appears as part of the public network, it is actually protected behind the router’s firewall on the
LAN network. That is, traffic between the public network and the host computer on the LAN is
still subject to the rules and policies configured on the router. A maximum of eight rules can be
defined.
Proxy ARP settings 25
To configure Proxy ARP, set the following options:
Enable ARP Proxy
Enables the feature on the router.
Name
A name (1 to 31 alphanumeric or special characters) that describes the Proxy ARP service. Do
not use these characters: ` " & ' # \
Popular Services
Selects common protocols that identify traffic that can be forwarded through the router to a host
computer on the local LAN.
Type
Selects TCP or UDP as the protocol type, or other special protocols. When Special Protocol is
selected, the protocol numbers can be entered in the Protocol field.
Port(s)
Specifies the TCP/UDP port numbers. More than one number can be entered separated by
commas.
Protocol(s)
Specifies special protocol numbers, separated by commas.
IP Address Of Public Hosts In LAN
The IP address of a computer on the local LAN. The IP address and mask can define a range of
addresses. For example, the IP address 10.8.0.100 with a mask 255.255.255.252 specifies
addresses in the range10.8.0.100 to10.8.0.103.
Subnet Mask Of Public Hosts In LAN
The local subnet mask for the IP address.
Rules Name
Applies a schedule rule to the Proxy ARP service. The schedule rules are configured on the
Tools > Scheduling page.

4 WAN configuration
The WAN pages are used to configure the parameters for your Internet connection. The
information necessary to set up a connection can be obtained from your ISP. Check with your
ISP first to find out what type of connection you should choose.
Viewing the WAN interface status
The Status page displays the setting of the WAN interface. If you are using DHCP as the
connection type, you can click Renew to request a new IP address.
This page includes the following information:
Connection Type
The router’s method of connection to the ISP.
Connection Time
The time elapsed since the Internet connection was established.
IP Address
The IP address assigned to the router’s WAN port by the ISP.
Subnet Mask
The IP subnet mask assigned to the router’s WAN port by the ISP.
Gateway
The IP address of the ISP’s gateway.
Primary/Secondary DNS Address
The IP addresses of primary and secondary domain name servers.
DDNS
The status of a dynamic DNS service.
MAC Clone
Indicates if the WAN port MAC address has been copied from a LAN computer.
Settings
The WAN settings page configures the method that the router uses to connect to an ISP through
the WAN port. The router supports five Internet connection methods.
DHCP IP address
DHCP is the most common method used to obtain an IP address with cable modems. In many
cases, setting the connection type to DHCP is enough to complete the connection to your ISP.
Some DHCP connections may require a Host Name. Enter the Host Name in the space
provided if you were assigned one by your ISP. Do not use these characters: ` " & ' # \
Some dynamic connections require that you clone the MAC address of the computer that was
originally connected to the modem. To do so, click on WAN > MAC Clone to set the WAN
MAC address. For more information, see
“MAC clone” on page 36.
This page includes the following information:
Connection Type
Select DHCP as the router’s method of connecting to the ISP.
Host Name
The host name assigned to the router by your ISP. The host name is optional, but may be
required by some ISPs.
Primary/Secondary DNS Address
The IP addresses of primary and secondary domain name servers.
Static IP address
Static mode sets the router to use a fixed IP address to connect to the Internet. If your ISP uses
static IP addressing, you need an IP address, subnet mask, and ISP gateway address. This
information is available from your ISP or on the paperwork that your ISP left with you. Enter
your information in the provided spaces, and then click Save.
