P/N 232-000373-00

Rev A 04/03

• XAUTH support for SecureID’s New PIN Mode, Next PIN Mode, and Next Token Mode

is excluded from this release.

• Changing the VPN keying method, for example, IKE to Manual Mode or Manual Mode to

IKE, can inadvertently change the subnet mask of the defined remote destination

network.

• Some wireless cards, notably Netgear and Linksys 54G cards, have demonstrated

compatibility issues when connecting to other manufacturer’s devices. Compatibility

issues are further complicated by the use of WEP, or by increasing the beaconing

interval beyond its default value. It is strongly recommended that you upgrade to the

latest firmware and device drivers available from your wireless client card’s

manufacturer, particularly if you are using Netgear or Linksys 54G equipment.

• By default, the TZW does not handle WLAN based WiFiSec tunneled packets larger

than 1,518 bytes (packets requiring fragmentation). If you are running a large packet

protocol (such as Kerberos or certain UDP applications), you must create a specific

access rule for that protocol, and enable fragmentation on that rule.

• Extremely heavy WiFiSec WLAN traffic loads could result in spurious IPSec Replay

Attack log messages.

• Changing the WAN interface mode, for example, from NAT Enabled to NAT with DHCP

Client while using DHCP services on the TZW can cause the current DHCP lease table

to be flushed.

• Attempting a configuration requiring wireless clients to connect to the TZW with a

WiFiSec connection, and the TZW then attempts to route all traffic through a VPN

connection to a hub termination point can result in failed phase 2 negotiations between

the hub and the TZW.

• Although validation and error-checking is implemented on all management entry fields, it

is strongly recommended that user names, service names, comments, etc. not contain

any non-alphanumeric characters such as apostrophes or backslashes.

• Internet Explorer 5.2.2 running on a Mac exhibits numerous page rendering problems.

When using a Mac for management, an alternative browser (e.g. Safari, iCab, Opera,

Mozilla) is recommended.

Microsoft Windows XP and the SOHO TZW

If you are running Microsoft Windows XP as your computer’s operating system, Windows XP, by

default, manages your wireless PC card settings. If you want to use the Microsoft wireless

management tools rather than your card vendor’s management tools, please note the following

information:

• Your wireless PC card drivers must be compatible with Microsoft’s Wireless Zero

Configuration service.

• You can access the wireless card settings by clicking on the wireless card icon in the

system tray, or by right-clicking on the My Network Places icon on the desktop and

double-clicking on the wireless card icon. When the initial configuration screen appears

it lists all of the wireless networks available. Click Advanced on the lower left side of

this screen.
