System information

TME 10 NetFinity manager with dedicated TCP/IP addresses and not configure
the access with any remote host access. This is very important, because if you
don′t restrict this access, then you might compromise security and your LAN
would be open to any Internet user, if this user has the TME 10 NetFinity code
installed and got information about one of your TCP/IP addresses.
Of course you may also install the Internet server on a different system and then
access a TME 10 NetFinity Manager which is physically installed on a different
managing workstation within the LAN. The address of this managing workstation
must now be known by the local TME 10 NetFinity manager, because this is now
the location address, which he or she will access with TME 10 NetFinity Web
Manager and
not the location address of the Internet server. Normally you have
a firewall installed to prevent your LAN from being accessed by a user from
outside via the Internet. In this case you cannot access a workstation connecte
to a remote LAN directly; the firewall omits this possibility.
See Figure 175 on page 147 for an overview of this connection. You will access
this server or the TME 10 NetFinity managing workstation by its Internet address.
Prerequisites on the remote location for this connection are the following:
1. All workstations have at least one supported network device driver installed.
2. All workstations connected to the remote LAN have at least the TME 10
NetFinity services installed.
3. One system, which is also connected to the remote LAN, has been
configured as an Internet server with the appropriate Internet connections
established.
4. The Internet server also has the TME 10 NetFinity Manager code installed or
one of the workstations within the LAN has the manager code installed.
5. The NetFinity Manager on the Internet server or the TME 10 NetFinity
managing workstation at the remote LAN has proper security configuration
set up so that the local TME 10 NetFinity Manager is allowed to access this
server. See 6.2, “Configuration of the Web Manager” on page 151 for
details on this configuration.
