Figure 179. Web Manager Configuration
Figure 179 shows the definition screen for the Web access to your gateway.
You at least have to enable the Web Manager and define a Web server socket.
•
Web Manager defines the status of the Web access to your gateway with:
− Enabled means that in general the access to your gateway from the
Internet is enabled.
− Disabled means that in general the access to your gateway from the
Internet has been disabled and
no TME 10 NetFinity Manager from
outside your LAN is allowed to access this gateway from the Internet.
•
Web Server Socket - In here you define the Web sockets, which are the
TCP/IP sockets. In our case, logical connection definitions for the Internet
access. Theoretically, this can be any numeric value, but the TME 10
NetFinity Manager that wants to access this gateway has to know this value.
The default value is 411, but you can define any value (0 - 32767). Most Web
servers use the socket number 80. This is the reason why TME 10 NetFinity
Web manager by default gives you a value of 411. This is to reduce the
chance of possible conflicts with your already existing Internet servers
sockets. We see later in this chapter how it is used.
•
Remote Access Restrictions - Defines who may access this gateway via the
Internet. You should always define the Web access to the TME 10 NetFinity
manager with dedicated TCP/IP addresses or address ranges and not
configuring the access with any remote host access. This is very important,
because if you don′t restrict this access, then you could get around the
security functions of the firewall and your LAN would be open to any Internet
user, if this user has information about one of your TCP/IP addresses. Of
course there are still the security functions of NetFinity, which prevent further
access than the main menu of the gateway.
