Configure Grip Server for Web Pages
Grip Server provides two different interfaces for client access: a UDP datagram interface
and a COM object interface. The router control web pages use both of these interfaces.
The web pages containing Java applets use the UDP datagram interface, with
communication occurring between the client machine's browser and Grip Server using
datagram packets. The active server web page (Basic Control Panel) uses the COM
object interface, with communication occurring between the Active Server Page script
program and Grip Server, i.e. the COM object interface is used for communications
between applications running on the server machine only, and is not used by client
machines to communicate with the server machine. (The Basic Control Panel is a static
html web page, with all content generated dynamically on the server machine using
active server pages).
The UDP datagram interface makes use of Internet UDP protocol port numbers 1234,
1235, 1244, and 1245. Grip Server sends datagrams to address 255.255.255.255, which
is a general broadcast address that all machines on the LAN (local intranet) receive.
These datagrams do not cross internet router or gateway boundaries, so this restricts use
of this interface to the LAN only. To ensure security of your router, you should configure
your gateways and internet routers to block any UDP datagram packet traffic on those
four port numbers! Other than that, no configuration is required for the UDP datagram
interface
.
The COM object interface must be configured using Windows XP Component Services:
1. Start Component Services: Press Start, Programs, Administrative Tools,
Component Services.
2. Open the Component Services icon within the Console Root folder.
3. Open the Computers folder within Component Services.
