If you are upgrading to this release from Release 5.61 or earlier, you will have to change your IP configuration in the 833IS. Releases 5.61 and earlier made the Dial in clients appear as if they were connected directly to the LAN, and the clients were assigned IP addresses from the LAN address space.

For releases after 5.61, the 833IS looks like a router between two networks. The first network is comprised of the devices on the LAN. The second network, referred to as the "Internal WAN network", is comprised of all IP clients and routers that are dialed into the WAN ports. Setting up a basic 833IS IP configuration requires the following:

Defining the network on the LAN side, and defining the address of the LAN router port.

Defining the network on the WAN side, and defining the address of the WAN router port. Note that all clients dialed into the WAN see the same address for this WAN router port.

Configuration details for this are contained in the readme file included in this release. Additional information is available from the online help facility of the 833IS Manager.

This upgrade must be performed from a LAN attached PC. Do not attempt this upgrade from a Dial in PC. To upgrade to this release:

Pre-upgrade steps.

1.Install the Release 6.0 software into a new directory on the PC.

2.Use the Manager to connect to the 833IS.

3.Upload the configuration from the 833IS and save it on a file on the PC.

4.If the 833IS is using a configured IP address, get the Server IP Address, Subnet Mask and Default Gateway (if applicable) from the IP profile screen in the Manager.
