Issue:
833AS: Providing Varied Levels of Security in LAN Level Remote Access Environments

Solution:

A 1.	What authentication methods does the Perle 833AS support with PPP? With PPP, the Perle 833AS allows support for both PAP and CHAP protocols. These authentication protocols can be setup for each user profile.
A 2.	What is the benefit of using IPX Network numbers? The benefit of using IPX Network numbers is that the system administrator can control the IPX frame type used by the remote IPX PC. This enables the administrator to make a distinction between internal and remote users on the network.
A 3.	Does the Perle 833AS support user password expiry dates and what is the advantage of having these? Yes it does. The main advantage to user password expiry dates is that no one has to remember to manually disable a user's profile at a specific time. Instead, an expiration date can be setup in advance for specific user profiles, giving only authorized users access to the corporate LAN.
A 4.	Does the Perle 833AS support RIP Version 2? Yes. The Perle 833AS supports RIP Version 1, RIP Version 1 compatible and RIP Version 2. RIP Version 2 protocol can control the method of authentication used, such as No Password, Plain Text Password or Keyed Message Digest (Encryption).
A 5.	Does the Perle 833AS support call-back and how does it help to increase LAN security? Yes it does. With call-back, a remote user dialing into central site must log-on with a password or identification number. The central site server then automatically terminates the connection and calls back the user at a telephone number that has been preprogrammed into the server. This added security measure is reliable for verifying a call from a particular site to help prevent unauthorized access, even if the user's password has been stolen.
A 6.	Can the Perle 833AS enable/disable protocols? The Perle 833AS can enable/disable at the server and/or user level, any of IP, IPX, NetBEUI, ARA, BCP and bridging protocols. This security feature limits remote users access to certain protocols. In effect, a firewall is created to provide a higher level of security.
A 7.	Why does the Perle 833AS support only IP and IPX filters? The standard for many companies has been to deploy multiple protocols in their network. In recent years, however, companies have moved towards establishing a single protocol network, predominantly IPX or IP. This reduces the costs and hassles associated with management and troubleshooting multiple protocol devices on the network, such as workstations, servers and routers. The trend lately has been more towards homogeneous IP networks.
A 8.	Does the Perle 833AS support static routing tables? Yes. The Perle 833AS offers the choice of using either static or dynamic routing tables to suit various IP and IPX protocol network environments.
