You may have to perform the following configurations to your local network or to certain computers on your network before users can access the Gateway Viewer application and share resources with remote Corente network computers.
For a local computer to participate in the Corente network, the IP address of the computer must be included in the Default User Group of your local Corente Virtual Services Gateway. Users will not be able to access remote computers when their computer is not included in the Default User Group. Similarly, if a computer is not included in the local Default User Group, it will be invisible to remote computers on the Corente network.
Additionally, in tube definitions to each Location partner, different local User Groups or applications can be matched with different remote User Groups or applications. In addition, Firewall Policies can be enabled on each tube that may limit how certain machines in the User Groups can access remote machines or be accessed by remote machines (or even whether they can access or be accessed at all). These "asymmetric tunnels" will affect what remote Corente network computers each user can access (and therefore, what remote computers their Gateway Viewer application will list) and how their own computer can be accessed.
To find out how to use App Net Manager to configure the User Groups, applications, and tubes of your Corente Virtual Services Gateway, refer to the section entitled User Groups, Applications, and Partners in the Corente Services Policy Definition and Provisioning manual.
As in all networks, there are two classifications for computers that participate in a Corente network: clients and servers.
Clients refer to computers that can access resources on other machines, but not share their own resources. Usually, this is the default configuration for Windows 98/Me.
Servers refer to computers that not only can access resources on other machines, but also provide resources (file, print, etc.) sharing themselves. Usually, this is the default configuration for Windows NT/2000/XP/Vista/7/8.
Only computers that support SMB-based file/print services and non-Windows computers will be visible on the Corente network. A Windows PC that is configured as a client will not be visible in the Corente network.
If you would like a Windows PC to appear in the Gateway Viewer and be visible on the Corente network, you should access the Network configuration for your computer and install the File and Printer Sharing for Microsoft Networks component on the system. As long as the machine is running file/print services, it will automatically be added to the Gateway Viewer.
If you want to add a machine to the Corente network but are unable to configure that computer to be automatically added to the Corente Network Neighborhood, you can add the computer using the Add Computers screen (see Section 2.10, “Add Computers”) to manually add it to the Corente network. Those computers added with this option must be manually removed using the Remove Computers screen (see Section 2.11, “Remove Computers”) available in the Networks menu.
If your location is using a Corente Virtual Services Gateway in a Peer configuration, you need to make the appropriate modifications to your network routing in order for computers on your network to function properly on the Corente network. Specifically, you need to change the routing infrastructure of your network to ensure that packets from your local network to all other remote networks within the Corente network are properly routed via your local Corente Virtual Services Gateway. Refer to the Corente Services Planning manual for more detailed instructions.
If your Corente Virtual Services Gateway is operating behind a proxy server, you must make sure that all Corente network users on your network change their web browser's settings to bypass the proxy server for local addresses and to specifically exclude the LAN IP address of the Corente Virtual Services Gateway. This must be done for every computer that will have access to the Location gateway. For instructions, refer to Appendix A, Accessing App Net Manager or Gateway Viewer from Behind a Proxy Server.
Windows computers that are on a different subnet than the local Corente Virtual Services Gateway can automatically appear in the Gateway Viewer if the router of that subnet can be configured to forward the UDP broadcast packets within its network to the Corente Virtual Services Gateway.
Otherwise, you can add computers on different subnets than the local Location gateway to Gateway Viewer using the Add Computers screen (see Section 2.10, “Add Computers”). Computers added with this screen will remain static in the Gateway Viewer; i.e., they can only be removed from the Gateway Viewer using the Remove Computers screen (see Section 2.11, “Remove Computers”).
