2. Recommendations when using this release

   Follow the Installation Guide for the OfficeConnect Cable/DSL Secure Gateway.

   For ease of use and installation, it is recommended that the OfficeConnect
   Cable/DSL Secure Gateway is used as a DHCP Server. This is the default
   configuration for the Gateway.

   In the interests of security, the administration password should be changed
   from the default setting.

   If required, you can download a strong encryption version of the software
   from the 3Com Web site. The strong encryption version can be identified by
   its filename; OSG0120-168.bin. The standard firmware is contained in the file
   called OSG0120.bin.

   For help in configuring IPSec, please download the document entitled
   "Creating IPSec VPNs with the OfficeConnect Secure Gateway", from the
   following 3Com Web site: http://support.3com.com

   In the unlikely event that the unit’s configuration becomes corrupt you can
   reset it using either of the following methods:
   - From the System Tools menu, select Restore to Factory Defaults.
   - The cable loopback method, described under "Forgotten Password" in the
     "Troubleshooting" section of the User Guide.
____________________________________________________________________________

3. Known problems with this release

   IPSec encryption is provided by software only. Please upgrade your firmware
   to a later version to enable hardware accelerated encryption.

   If the DHCP Server ever allocates a new IP address to a device that should
   have a fixed IP address, you can resolve this by restarting the Gateway then
   restarting the device.

4. Upgrading to this release
  
   Although the upgrade process has been designed to preserve your configuration
   settings, 3Com recommends that you make a backup of the configuration
   beforehand, in case the upgrade process fails for any reason (for example,
   the connection between the computer and the Gateway is lost while the new
   software is being copied to the Gateway).

   Instructions for upgrading the OfficeConnect Cable/DSL Gateway:
   1. Ensure the Gateway is powered and a link is established with the host PC.
   2. Ensure that the latest version of the Gateway code is located on the host
      PC. The latest version of the OfficeConnect Cable/DSL Gateway software can
      be obtained from the 3Com Web site.
   3. Launch a web browser to the IP address of the Gateway and login.
   4. Select 'System Tools' from menu bar on the left hand side of the screen.
   5. Select the 'Upgrade' tab.
   6. Browse to the location of the Gateway code, select the file and press the
      Apply button. You may need to change the file type in the dialog box
      displayed by your web browser to *.* to be able to see the file.
   7. Wait for the upgrade process to complete. This may take several minutes
      and is complete when the Alert LED has stopped flashing and is permanently
      off.
