Access and Application Support

Many advanced a pplications are provided by the RoamAbout R1, such as:

• Flexible LAN Access

The RoamAbout R1 pro vides connectivi ty to 10/100 Mbps wired device s, as well as 11
Mbps wirele ss mobile user s. The wireless interface ma kes it easy to create a network in
difficul t-to-wire environmen ts, a nd to provide quick acces s to datab ases for wire les s users.

• Internet Access

The RoamAbout R1 supports Internet ac ce ss through an xDSL, Cable, ISDN or PSTN
connection. Many DSL provi ders use PPPoE to establish communications wit h end users.
The RoamAbout R1 includes a built-i n client for PPPoE which el iminates the need to install
this service on your computer.

• Shared IP Address

The RoamAbout R1 pro vides Internet access f or up to 32 us ers with a shared IP address.
Multiple users on your network can browse the Web at the same time using only one ISP
account.

Access and Application Support

• Virtual Server

If you have a fi xed IP addre ss, you can s et u p t he Roam About R1 to act as a virtua l host f or
network address translation. Remote users can access various s ervices at your site using a
constant IP address. Then, dependi ng on the requested service (or port numb er), the
RoamAbout R1 can route the request to the appropriate server (at another internal IP
address). Thi s se cure s your network from direct attack by hacker s , and provides more
flexible management by allowing you to change internal IP addresses without affecting
outside access to your networ k.

• User-Definable Application Sensing Tunnel

You can define special applicat ions that require multiple connections such as Internet
gaming, videoconferencing, and Internet telephony. The RoamAbout R1 senses the
application type and opens a multi - port tunnel for it.

• DMZ Host Support

DMZ (Demilitarized Zone) allows you to open up a client PC for two-way unrestricted
Internet acces s. For example, you would use th is feat ure i f yo u ha ve a cli ent P C tha t cannot
run an Internet application properly from behind the NAT firewall or after configuring the
special applications feature. Using this feature creates a security risk and s hould only be
used as a last reso r t .

1-3

Access and Application Support

• Security

The RoamAbout R1 supports security features that can de ny Internet access to specified
users, or filter all requests for specific services. The RoamAbout R1’s firewall can also
block common hacke r attac ks, i ncludi ng IP Spoofi ng, Land Atta ck , Ping of Dea th, IP with
zero length, Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP
SYN flooding.

• Virtual Private Network

The RoamAbout R1 supports three of the most commonl y used VPN prot ocols – PPTP,
L2TP and IPSec. These protocols allow remote users to establish a secure connection to
their corporat e ne twork. If your service provid er supports VPNs, then any of these
protocols ca n be us ed to create an authenticated and encrypted tunnel for passing secure
data over the Internet (i.e., a traditionally shared data network). The VPN protocols
supported by the RoamAbout R1 are briefly described below.

— Point-to-Point Tunneling Protoco l – Pro vides a secure tunnel for remote

client access to a PPTP security gateway. PPTP includes provisions for call
origination and flow control required by ISPs.

— Layer Two Tunneling Protocol – Includes most of the feat ures provided by

PPTP, but has less overhead and is more suited for managed networks.

— IP Security – Provides IP network-layer encryption. IPSec can support large

encrypti on networks (such as the Internet) by using digital certificates for
device authentication.

LAN Connections

The three LAN ports on the RoamAbout R1 can auto-negotiate the connection speed to
10 Mbps Ethernet or 100 Mbps Fast Ethernet, as well as the transmission mode to
half-dupl ex or full-duplex. These LAN ports also support auto-configurat ion for pin signals
(auto-MDI/MDI-X) that allows you to use straight-through cable for connecting the
RoamAbout R1 to any network device. Refer to the RoamAbout R1 SOHO Setup and
Installation Guide.

Use twiste d-pair cable to connect any of the three LAN ports on the RoamAbout R1 to an
Ethernet adapter on your PC. Otherwise, you can cascade any of LAN ports on the
RoamAbout R1 to an Ethernet h ub or switch, and then connect your PC (or other network
equipment) to the hub or switch.

Network Address Translation – NAT

Network Addre ss Tra nslation ca n be used to g ive mu ltipl e use rs ac cess t o the I nterne t wit h
a single us er account, or to map the local ad d ress for an IP server (such as Web o r FTP) to
a public address. This secures your network from direct attack by hackers, and provides
more flexible management by allowing you to change internal IP addresses without

affecting outside access to your network.

NAT must be enabl ed to p rovid e multi-u ser acc ess to the Inte rnet , or to use

NOTE

the Virtual Server function.

Virtual Server

If you configure the RoamAbout R1 as a virtual server, remote users acces sing services
such as the Web or FTP at your local sit e via public IP addresses can be aut omatically
redirected to local servers conf igured with private IP addresses. Depending on the
requested servic e (TCP/UDP port number), the RoamAbout R1 redirects the external
service request to the appropriate server (located at another internal IP address ) .

The WAN interface must have a fixed IP address to utilize this function. For example, if
you set T ype/Publi c Port to TCP/8 0 (HTTP o r Web) and the Pri vate I P/Port to 192. 168.2. 2/
80, then al l HTTP re ques t from o utsid e use rs wil l be t ransfe rred to 192. 168.2. 2. The refore,

• FTP: 21

• Telnet: 23

• POP3: 110.

Remote Management

By default , management access is only available to us ers on your local network. You can
manage the RoamAbout R1 from a remote host by adding the IP address of an admin istrator

in the Remote Management page.

NOTE

• If you spe cify an IP address of 0.0.0.0, an y ho st in your local n et work can

manage the RoamAbout R1.

• Only one management se ssion can be logged in at a time. You must log o ut
