Performs IP and IPX
routing and bridging.
Functions as a “Solid
Firewall.”
“Single IP” connects
LAN users to the
Internet or an intranet
through just one IP
address.
WAN links can be dial-
up, leased line (DDS or
full or fractional E1 or
T1), or Frame Relay.
Supports PPP, HDLC,
RFC 1490, SNMP, PAP,
and CHAP, as well as
T1/E1 drop & insert.

f your network users want
access to the Internet, or to the
company intranet, there’s always
someone ready to sell you a
solution that doesn’t do what you
need, includes bells and whistles
you don’t need, and whose installation and maintenance costs will
wipe out your budget twice over.
Before you put yourself
through that, try our Internet
Access Router 2 (IAR 2) on for
size. It’s a router you can hook up
to one or two Ethernet LANs in
order to WAN-link them to an
external IP internetwork. For the
price, the IAR2 is remarkably fullfeatured—
with the good stuff:
• Its IP routing includes
support for static IP configuration,
dynamic IP learning with RIP and
RIP-2, CIDR topologies, multiple IP
nets on the same LAN, numbered
and unnumbered interfaces, and
IP fragmentation.
• Its IPX routing includes RIP
and SAPsupport.

• Its bridging is IEEE 802.1d
compliant (but does
not
include
the Spanning Tree algorithm). It
can bridge two LANs across the
WAN link, opposite any standard
third-party bridge; two-LAN units
can bridge those two LANs also,
or even all three LANs at once.
• As a “Solid Firewall,” it
makes your local LAN totally
invisible to unauthorized outside
users, which makes it ideal for
security-sensitive offices. External
logins can be handled with the
PAPor CHAP protocol.
Probably the most useful and
exciting feature of the IAR 2,
though, is “Single IP.” Normally a
LAN requires a complete, unique,
legal, statically assigned subnet to
connect to an external IP
network. But with Single IP, your
entire small office can access the
Internet or an intranet the same
way a single PC would: by using
just one IPaddress, statically or
dynamically assigned by your ISP.
This means that any of the
users on your network can run a
Web browser, FTP client, email
client, news reader, Telnet,
TN3270, or other IP application
using any TCP/IP stack on any
type of computer. Several of them
can even do this simultaneously.
The IAR 2 can also connect or
disconnect from its WAN link(s)
based on actual or specific usage,
and it can filter traffic to avoid
wasting bandwidth.
On the LAN side, different
models of the Router have either
one or two 10BASE-T ports or one
10BASE2 (ThinNet) port. On the
WAN side, different models have
either one E1 port, two E1 ports
(one main and one sublink), one
T1 port, two T1 ports (one main
and one sublink), one V.35 port, or
one X.21 port. The E1 ports have
both balanced (RJ-45) and unbalanced (dual BNC) connectors for
maximum compatibility.
